Colored text is a very nice thing after a linux penguen welcomes you while booting. Please don't remove it

3. Is the git going to be up any time soon?
4. Do you have the patch handy to create the colored text?

answer to question 1: they stopped naming their kernels by zen version. instead the same version gets updated every time in git until a new vanilla kernel comes out. so, no more 2.6.38-zen0, instead 2.6.38-zen and if there's an update for the kernel the version number remains the same until 2.6.38.1 comes out. then it becomes 2.6.38.1-zen
so, there are a total of 3 .38 versions: 2.6.38-zen, 2.6.38.1-zen and 2.6.38.2-zen

Please post the links for the first two, as I have the link already for 2.6.38.2-zen. I'd like to make seeds for them all. It's sort of a tradition.

Cheers,
Pappy

Thanks for the link. Now I can run it on my personal sources, whether zen, or vanilla. Woohoo! You have made me happy to be a geek yet again.

Cheers,
Pappy

EDIT: I spoke too soon. The versions at that site are old. Anyone know where I can get something that will work with the .38 family??? /EDIT

/EDIT-2: apparently, I don't need to patch for this since 2.6.38.2-zen added it. Nice! Time to update again./EDIT-2

2.6.38.1-zen with latest commit before 2.6.38.2-zen: http://git.zen-kernel.org/zen-stable/sn ... f5.tar.bz2

2.6.38-zen with latest commit: http://git.zen-kernel.org/zen-stable/co ... 63aa301c0d

note that 2.6.38-zen wasn't patched a lot, the only config for improving performance in this version that was not in vanilla kernel is zen tune. another thing, the older versions aren't available for download in git tag. you can only download an older version by looking at a commit before the upstream update.

raj7095 · Post by **raj7095** » Tue Apr 05, 2011 1:20 am

oh and the latest, updated version for zen kernel 2.6.38.2-zen is right here: http://git.zen-kernel.org/zen-stable/sn ... 21.tar.bz2

Any way to update using git?

Why is git down so often? Gitorious mirror is not up to date.

Anybody using reiser4 with the latest zen? I'm getting: reiser4_inflate_cluster (fs/reiser4/plugin/file/cryptcompress.c:1136)[edward-1460] errors...

If anyone's getting tired of zen might I suggest pf-sources.
https://github.com/pfactum/pf-kernel
http://pf.natalenko.name/

It's main advantage over zen seems to be that it's updated VERY promptly, has a reliable host, and is basically just a vanilla kernel with some of the more popular patches applied (BFQ, BFS).

I haven't been able to fetch zen for about a month so I assume it's dead (or my DNS is screwy), though possibly just the public server since I notice somebody is still making commits now and then on the cgit. I haven't checked the snapshots.

if the main repo is down I can't update it: I got no git hooks configured for that so I'm trying it whenever I spot updates

raj7095 · Post by **raj7095** » Sun Apr 10, 2011 4:24 pm

there is another way to update the zen kernel without the git. grab the latest patch from http://downloads.zen-kernel.org/snapshots/
and then patch vanilla kernel with it. if you see that its updated, reverse the old patch with "patch -R -p1 < ./(nameofpatch)", delete the patch file and then apply the new patch.

Does anybody else have problems with reiser4 on 2.6.38? On 2.6.37 everything works fine...

lkraav · Post by **lkraav** » Mon Apr 18, 2011 9:20 pm

negative on the reiser thing, havent had a kernel panic anymore with btrfs for a while.

did have one occurence of ehci_hcd saying "HC died" and poof there went my usb ports inoperable.

so when's the next ebuild coming up with a snapshot including BFS400?

ponciarello · Post by **ponciarello** » Tue Apr 19, 2011 5:06 am

FYI, Con Kolivas answer on differences between bfs-376 and bfs-400.

for a snapshot patch to apply on 2.6.38 you need to issue a command like this from the git tree

Code: Select all

git diff v2.6.38 master | xz -z -c > /tmp/2.6.38-zen-snapshot-patch.xz

I'm trying to keep this updated with the mirror (so I have a downoad point for my needs)

lkraav · Post by **lkraav** » Tue Apr 19, 2011 6:51 am

thanks, its gonna take me a few days at least to get to manual patching.. hopefully hwoarang will come up with .3 and bfs400 ebuild by then

zcache + fixes + make btrfs work and tweaks & improvements to zram (included in 2.6.39)

to be applied on top of 2.6.38.3-zen*

md5sum:

Enjoy !

to enable it you need to append zcache to your kernel in grub.conf, lilo.conf,
