unofficial linux-ck repo with cpu optimized packages is ONLINE

kokonut · 2015-08-06 05:33:22

For any BTRFS users like me, scrubbing once again can cause deadlocks. According to ck's blogspot comments, here, it might be necessary to apply http://ck.kolivas.org/patches/bfs/4.0/4 … gged.patch again.

I am going to go test that.

graysky · 2015-08-06 07:37:21

@kokonut - Please do and report back.

I am the Anonymous in ck's blog comments.

I btrfs scrubbed three times in a row while web browsing using a kernel with that patched and everything now seems fine. So I assume the patch fixes the deadlocking issue.

I would include as part of the linux-ck packages.

Is anyone else having crashes on 4.1 similar to the ones experienced with early 4.0 versions? On the linux-ck 4.1 kernel on my netbook (bobcat processor family) it crashes on boot about half the time and under high IO loads. I'm currently testing similar conditions on the stock Arch kernel, and if it runs clean for a day or so more, I'll probably post on the ck blog with this issue.

As I comment on [1] I have BTRFS and I disabled NUMA and applied the patch from comments on ck blog. Couple of scrubs, kernel compilation and working with Citrix all day - no issues. I have AMD.

This is great to hear, inglor. Thank you for testing this. To others who have experienced these issues in the past, please do two things for testing:

1) Uncomment the code in the PKGBUILD that allows you to disable NUMA and do so.
2) Patch the code with CK's testing patch.

I have made it easy for you, just download this patch which will modify your PKGBUILD for version 4.1.4-1 which is the current version. Execute it like so:

cd /path/to/PKGBUILD
wget https://gist.github.com/graysky2/cd637b026d4cf1649048/raw/776bd11edf983a6ebc33c39be53b13cb52f2385a/try_ck_panic_fix.patch
patch -i try_ck_panic_fix.patch

Now just makepkg -src as usual. Please report back in this thread and thanks!

I don't use BTRFS, but in the past I had kernel panics using linux-ck with NUMA disabled. It's now a couple of hours that I'm running the patched linux 4.1.4-ck (no BTRFS) using BFQ and it seems to work well: no panic occurred so far. I will continue to test it and I'll report back if there is any problem.

--edit: Nevermind, a kernel panic occurred just now on shuthdown.

Apologies if this has already been asked - any idea what happened to acpi_call-ck? I don't see it in AUR anymore.

runical · 2015-08-09 18:20:28

The AUR was moved to version 4 yesterday. Packages that have not been reuploaded to the new AUR are no longer in the AUR. This includes a lot of abandoned packages (and probably the package you are asking for).

All the packages seem to 404 at the moment. Pacman still lists 4.1.4 after running -Syy.

fungle · 2015-08-12 22:22:12

The repo-ck.db seems out of date. Linux-ck is trying to update to 4.1.4-2 which 404's. Downloaded the db file manually and untarred it and it shows version 4.1.4-2 instead of 4.1.5 to reflect the repo.

@fungle - Odd. I just reindexed and pushed. Please try now.

I found that I need it 1 year after. I am too lazy to compile the kernel and I have to use generic now

I have a Core i3 350M, so it should be westmere, too. Since it is also called Nehalem-C, I am currently testing the nehalem build and it seems to work just fine.

Any chance of compiling with LZ4 enabled? I don't know much about compiling kernel, but it's just switching one flag right?
zswap is failing when using LZ4:

zswap: lz4 compressor not available
zswap: using lzo compressor

Using the exact same system with the official kernel works just fine.

Not a big problem, would just be nice to have

EDIT: I'm an idiot! I've only used mkinitcpio per installation instructions - I had no idea linux-ck would need it's own initramfs.
Got it all fixed by running mkinitcpio -p linux-ck. I feel stupid.

Old post is below.

That's odd. Any clue how I'd go about debugging this? I have both kernels in my grub menu using the same initramfs yet they give different results.

Yes:

EDIT: That's odd. mkinitcpio doesn't say anything about adding the lz4 module (I'm sure I remember seeing this in the past):

Is mkinitcpio not respecting my MODULES array?
Still doesn't explain the fact it works using the official kernel though?

graysky, could you plz enable CONFIG_EXT4_ENCRYPTION in ck kernels?
(it's not eanbled by default)

graysky · 2015-08-30 11:18:50

@chaonaut - I like to mirror the official config as much as possible. Can you please a request against the official kernel to do so? Also, didn't I read somewhere that no userspace tools for this feature are available yet?

Apparently, it looks to be not natively enabled or something. This is what the ArchWiki says on the issue.

well, never mind, it's not a big problem for me to rebuild the kernel package.

this applies to e2fsprogs, not kernel.
btw, it works

graysky · 2015-08-30 15:03:40

@chaonaut - If that feature is useful, and if support by current userspace tools, please create a feature request against the ARCH linux package. If accepted, I will as well.
