great patchset!

...unfortunately i'll be sticking to -kamikaze3 since I need the hrtimers patch (it's so hard to find support for amd64 dynticks anywhere else!)

Linus Torvalds rejected hrtimers for 2.6.23 so might have to wait some more before it makes it to vanilla...sigh.

Bad link to ebuild - should be http://kamikaze.waninkoko.info/ebuilds/kamikaze-sources-2.6.22-r5.ebuild (missing last r

)
Great patchset !

Works great here! Memory usage is quite low too.

Hi, this is great!

I want to try to patch a kernel myself.I just want cpuidle, suspend2 and powertop patch, but I don't know how to find those patch, suspend2 has a website, but the others?
and what the ipw2200 patch do? or where could I found it?

I have been looking for a replacement for the beyond-patchset, and I think I found a nice one...

I would go with klight as I prefer stability over bleeding edge, but then I'd miss suspend2/tuxonice. (and I am to lazy to build one on my own.)

apropos suspend2: I do have some problem getting it to work. It causes massive kernel panics and lockups (if using using the plain suspend2-sources, or kamikaze4 at boot time already). Does any else experience this? Running on amd64 to which I am new, but i know how it should work from my old laptop (which died recently)
I would post a trace, if there is a easy way to get it from the logs. How do i do this?

cheers
V.

Won't compile here. IPW3945 complains:

Working great here! Thanx.

I'm also back to reiser4 w/cryptcompress lzo from ext4.

My ext4 partition recently failed because of a kernic panic on ext4's boot sequence whenever there was a unclean unmount. I warn people to stay away from ext4 for their / partition. fsck.ext4 would just seg fault.

Observations on ext4 vs reiser4 w/cryptcompress lzo:

ext4 with -o extents,delalloc is really fast at emerge --sync and the portage database rebuild. ext4 is light years ahead of ext3 for small file performance. It also has really good interactivity because of low cpu overhead. The delayed allocation option makes my hard drive do a lot less work and saves even more CPU.

reiser4: faster than ext4 when my CPU isn't being used up. reiser4 does emerge --sync faster than ext4. reiser4 saves a lot of space (my root went from 8GB to 4.1GB). Unfortunately reiser4 is not as responsive sometimes because of high cpu usage.

I would consider reiser4 stable now.. but it's future is unknown (it will never make it into mainline).

ext4 is awesome and fast without compression, reiser4 without compression isn't as impressive. but ext4 is unstable and not suitable for any important data (to be expected because of it's beta nature).

My root is now reiser4, but I hope they get ext4 w/ compression soon, and make it stable.

one note: I dislike the CFS boost - autonice to -10 patches because Xorg as well as many kernel threads and modules get niced to -10... Whenever my ipw2200 wireless card is busy scanning for an AP it uses 100% of my CPU and slows everything down since it's at -10.

kamikaze5 works fine for me. the only thing is it crashes on boot if DMIID enabled since kamikaze3

Dynticks on x86_64 working great! Thanks!

ok, so setting IPW3945_COMPAT to 2 does work. I'd still like to know why that value...

Kernel works well. Suspend to disk still doesn't work properly (when resuming it gives me a gray screen and doesn't accept any input other than ctrl-alt-del). Suspend to ram works nicely, which makes my life happier.

For anyone who is lazy (like me) here's a patch to add the aforementioned "#define IPW3945_COMPAT 2" to fix ipw3945.

This kernel still lacks of correct ibm-acpi support. I can't even access my fn-keys. I tried gentoo-2.6.22-r2 and with that one it works. So one of the patches screws it up. What patches do affect acpi? Is it only thinkpad?

If I reverse the thinkpad patch the hotkeys do work again... I'll find out what part of the patch affects this problem, because a lot is in that patch actually.

I'm still experiencing hard locks in X with this kernel on my x86_64 machine. Works fine with gentoo-sources-2.6.22 or ragnarok-sources.2.6.22.... I've tried disabling dynticks and high precision event times as well as changing from slub back to slab. however it had no effect. Anyone else experiencing this? any ideas on some patches I might try to reverse? maybe adaptive read-ahead? Suggestions are welcome. I can post my .config and whatever else if needed...

I've always had issues with adaptive read ahead, even though it's changed so many times I just don't bother with it anymore

I noticed those errors when compiling ipw3945 (I updated it very quickly) :S

PD: I'm not back of my holidays

But I'll be back soon (10 days).

System competely freezing not even responding to pings never mind trying to ssh in

This has been happening for a v long time since it was newly intoducted into the "experimental" patchsets on here.

I gave up on it I haven't tried it recently

I tried to compile this kernel...
at first I couldn't compile ipw3945 driver, but with adding the line mentioned above it works.

BUT, when I try to start my system I get something like:
VFS: unable to mount root fs via nfs trying floppy...
... not syncing ...
Specify a correct root

(kernel panic)

I did specify a correct root, because with other kernels it works.
But now I get a message that /dev/sda7 not exists (while with another kernel it works)

Also I get some message in the boot process that I have a 1.4MB floppy (which is not true)

Could someone point me in the right direction to search for?

Greetings!
