  4.12 Memory allocation issue
Posted by: LTM - 14-07-2017, 10:45 PM - Forum: Bug Report - Replies (5)


I have installed the latest 4.12 kernel on 9 dedicated servers.
it seems that there is an issue with the memory allocation (we have this problem now on 2 servers).
After running without any issues for about 12h, the server goes to swap (it uses for no reason 50% of the ram)
I have shut down every process and it still uses 50% of the ram (256gb out of 512gb).

  Laptop-mode config needs adjustments for xanmod!
Posted by: GWD72 - 11-07-2017, 08:50 AM - Forum: General Discussion - Replies (7)

Hello forum followers!

I thought it could be useful to notify here that laptop-mode users need to make some changes to the /etc/laptop-mode/laptop-mode.conf file in order that it will continue the enhancements offered by xanmod kernels!

I am currently using 4.11.9-xanmod13.

The config for laptop-mode can now be identified as blocking the dirty_ratio and dirty_background_ratio (for example) implemented by xanmod (although this can be fixed).

To the point, what I changed and noticed improvements which were most apparent on my HP mini 210-1000:

1) XFS_HZ=500 (default was 100) NOTE: I assume this is the same frequency as that by which the xanmod kernels are compiled.  If this is WRONG, no problem for me, do make corrections please!

2) CONTROL_MOUNT_OPTIONS=0 (default was 1) NOTE: this disables laptop-mode changing tuned fstab mount options (I use my own mods and was previously oblivious to the fact that my tweaks were being over-riled by laptop-mode tools).

3) LM_DIRTY_RATIO=20  (default was 40)
    NOLM_DIRTY_RATIO=20  (default was 60)

4) LM_DIRTY_BACKGROUND_RATIO=5  (default was 1)
    NOLM_DIRTY_BACKGROUND_RATIO=5  (default was 10)

5) CONTROL_HD_IDLE_TIMEOUT=0   (default was 1)

6) CONTROL_NOATIME=0  (default was 0 or 1)
    USE_RELATIME=0  (default was 0 or 1)
NOTE: I use noatime in mount options specified in fstab.  If you do not want laptop-mode tools to meddle with your fstab mount options, turn these off also (i.e. use a value 0) and see 2) above.

7) CONTROL_READAHEAD=0  (default was 1)

NOTE:  one needs to think about other systems settings on "their" environment and not blindly follow this since each system/box can and will be set up differently.  I accept no responsibility for anyone using the settings I found helped me!

I need to survey further with more usage, but making these changes seems to allow xanmod to do its thing performance-wise while still observing decent battery savings.  Of course, "you" may find a different end result.

In addition, there are some further tweaks I think could be made, and perhaps those associated with xanmod could comment?

For example, these following values are defaults in the laptop-mode config file, but I've no idea if they match those of the native 4.11.9-xanmod13:

# kernel default settings -- don't touch these unless you know what you're
# doing.

Are these values xanmod uses, or, should they be adjusted in order to match?

  Kernel panic after start any Virtualbox VM [solved]
Posted by: figue - 09-07-2017, 10:31 PM - Forum: Bug Report - Replies (3)

Hi, I'm running 4.12 xanmod on Archlinux. I use default xanmod config and build with default GCC 7.1.1.

A kernel panic happens when I try to boot any Virtualbox VM. With Arch stock kernel or xanmod 4.11.x series all is OK.

I can only take a photo of the kernel panic (please excuse the quality).

  BFQ may not ready for the production environment
Posted by: HougeLangley - 09-07-2017, 04:52 AM - Forum: General Discussion - Replies (5)

These days I noticed that many things about the new I/O Scheduler. 

The first one, BFQ not default in the new version kernel 4.12. We should use a litter trick. I see one way from here. And the best way is using Xanmod kernel. BTW, Thank you, Xan.

The second one. A benchmark test I have been noticed from Phoronix site. BFQ and Kyber I/O scheduler not good enough in those tests. What do you guys think these tesets?

The third one, BFQ not stable for now. I think you guys have been noticed that the re-new version xanmod kernel. For now, I using mq-deadline instead of BFQ and Kyber. I found if edited the /etc/default/grub like this:

GRUB_CMDLINE_LINUX_DEFAULT="scsi_mod.use_blk_mq=1 elevator=mq-deadline zswap.enabled=1 zswap.compressor=lz4"

After I boot and check io scheduler. The default one is BFQ. So, I edited /etc/rc.local and using .sh file to changed default io scheduler after boot. My .sh file like this:

echo mq-deadline > /sys/block/sda/queue/scheduler

After boot and check it.

hl@hl-Inspiron-15-7000-Gaming ~ $ cat  /sys/block/sd*/queue/scheduler
[mq-deadline] kyber bfq none
[mq-deadline] kyber bfq none
hl@hl-Inspiron-15-7000-Gaming ~ $

Any idea changed the defalut io scheduler using better way. Thank you.

  vm settings question
Posted by: GWD72 - 23-06-2017, 01:41 PM - Forum: General Discussion - Replies (4)

Hello forum followers!!

I have a question about the "vm" settings using 4.11.6-xanmod9.

Prelude: I have assumed (perhaps incorrectly) that (from

- Set VM cache pressure value to 50%.  means vm.vfs_cache_pressure = 50
- Set VM swappiness value to 10%.       means vm.swappiness = 10
- Set VM dirty background ratio to 5%.  means vm.dirty_background_ratio = 5
- Set VM dirty ratio value to 20%.         means vm.dirty_ratio = 20

Is that correct?  I am asking because when I run "sysctl -a" in terminal, I actually see what I think are default values for vm.dirty_background_ratio and vm.dirty_ratio, which carry values of 10 and 40 respectively.

I would have expected to see vm.dirty_background_ratio = 5 (not 10) and vm.dirty_ratio = 20 (not 40) if I am looking at this correctly, whilst running the 4.11.6-xanmod9 kernel.

I had previously (well before ever hearing about xanmod) set in sysctl.conf my own values of vm.dirty_background_ratio = 2 and vm.dirty_ratio = 15, but as I have just learned today, those values have never been used (now that I am aware of the "sysctl -a" command).

So it seems ubuntu is using some default values instead of those dictated by the 4.11.6-xanmod9 kernel.  Is anyone else seeing this?

Is there a way to force my system to use vm.dirty_background_ratio = 5 and vm.dirty_ratio = 20, for example?


EDIT: perhaps it is a bug in ubuntu due to pm-utils? (

  can't connect to network drive 4.11.6-xanmod9 x86_64
Posted by: GWD72 - 20-06-2017, 09:47 AM - Forum: General Discussion - Replies (9)

Hello forum followers!

I am running Ubuntu LTS 16.04 and the xanmod 4.11.6 kernel (and loving it!) but have just found my connection to my netdrive is giving this error:

Oops! Something went wrong.
Unhandled error message: Failed to mount Windows share: Invalid argument

I confirmed this also on my wife's laptop.  Reverting back to the generic environment, currently on the 4.4.0-81 kernel, I can successfully connect to my net drive.

Please fix!!   Big Grin

  i5-2410 no turbo xanmod 4.4-71
Posted by: GWD72 - 15-06-2017, 05:42 AM - Forum: General Discussion - Replies (7)

Hello forum followers,

I am new here, and after searching for my problem I found nothing so here is my post.  Apologies in advance if this should go to bug reports!

I run ubuntu 16.04 LTS and decided to try xanmod 4.4.-71 LTS with my HP 2560p running an intel i5-2410.  This CPU is standard 2.3 GHz with up to 2.9 GHz turbo.

When running with the 4.4-71 kernel, turbo is not available!  I see no higher CPU frequencies than 2.3 GHz.  For now I have unistalled everything and reverted back to the current native kernel (4.4.0-79-generic x86_64) but I would really like to try this xanmod and find out for myself how much better bfq is!

I can find nothing about this issue anywhere!  If anyone might have insight as to why this is a problem, please share.  I am willing to experiment to get it working!  My system is customised heavily and it could just be that some tweak I have made in the generic environment is messing up the xanmod environment.

An additional note that the update to the intel microcode installed a 2016 version, when if you go to the intel pages, my CPU microcode is from 2015.  I replaced the original microcode (3.20150121.1) from 3.2016.1104.1 (which I removed), but that did not solve the issue.

Edit: here is the read out from lscpu |egrep "Model name|MHz":

with xanmod kernel:

Model name: Intel® Core™ i5-2410M CPU @ 2.30GHz
CPU MHz: 2300.000
CPU max MHz: 2301.0000
CPU min MHz: 800.0000

without xanmod kernel:

Model name: Intel® Core™ i5-2410M CPU @ 2.30GHz
CPU MHz: 831.593
CPU max MHz: 2900.0000
CPU min MHz: 800.0000
