Hi. I'm running kamikaze3 and everything works great.
How come is cpuidle new patch? It is in kamikaze3 also. With it (menu governor) my cpu finaly goes into c3 while using wlan.

I'll stick with kamikaze3, since I don't have a laptop, and no HRTIMERS means no dynticks as well. In my AMD64 dynticks work just fine.

You forgot to change version number

A little mistake.

kamikaze4 was released to check if the problems of kamikaze3 are caused by hrtimers patch.

PD: I thought dynticks for x86_64 were added in 2.6.21.

Unless I am mistaken, in kamikaze4 there no option for dynticks, only way for this to be there is if it is enabled by default for AMD64, without any visible optiion, but I doubt it.

dynticks landed in 2.6.21 but only for i386. x86_64 dynticks was supposed to land in 2.6.22 but didn't and it seems not to land in 2.6.23 either.

Nice work!
I'm testing now with the 'official' reiser4 for 2.6.22: http://lwn.net/Articles/242582/ Looks good so far...Thanks!

Working great here, I was having some issues with kamikaze3 on my amd64 machines (X freezing after some moderate to heavy usage)... anyways all is well now. Cheers

Waninkoko, could you please create a .tar.bz2 file for your broken-out files in the future it's sometimes a real hassle downloading several files if the server is overloaded or during other circumstances

many thanks in advance & thanks again for your great patchset

it's not... Here's a link to the reasoning for that

Gonna build this puppy tonight... Thanks for your work waninkoko... Much appreciated

Waninkoko, is that the official reiser4 patch you're using ?

Nope.

k, just tested the latest 2.6.22 patch from namesys and I must say: they did a fairly good job, there's no more data loss (at least on normal reiser4, haven't tested cryptcompress yet)

so for future releases could you please use reiser4-patches >= from 23rd of July / from mm with latest fixes
this way reiser4 is pretty usable

I confirm that

Works fine here with my self-made patchset: 2.6.22 +ck +R4 from namesys

Ok, new reiser4 patch will be in kamikaze5 (31st July

).

and also please in the next klight release (whenever that will be), I'm waiting for the next grsecurity-patch which unfortunately doesn't work with this heavy patched kamikaze-kernel

thanks, though

O.K. I'm done with kamikaze4 !
I've encountered system freeze, once again... X was frozen and only blinking keyboard leds... The very same situation as I had with kamikaze2 and 3 with intensive workload - amarok + quanta + apache + mysql + opera + firefox + emerge running at nice 15. I suspect that it's the very same bug as with previous releases and it may have something to do with CFS or hrt. The last time I've managed to catch some panic logs on console it was spiting something about sched_atomic stuff...

As soon as I'm done with reiserfsck I'm gonna see if there were some logs saved...
I will better stay with less experimental patchset

or switch back to some 2.6.21-ck series - if there is still anything usable left on my system partition...
P.S. kind a weird felling writing post from console (links2)

EDIT: not a single panic nor bug log in /var/log

cca · Post by **cca** » Sat Jul 28, 2007 9:49 am

If you froze with kamikaze4, it's not the hrtimers, since that release is devoid of that patch. Have no clue what could be happening.

Well, it could be.... CFS?

Seriously though, on some heavy loads you do get crashes sometimes - both with SD and CFS (at least on my computer) [and much much more crashes on current mainline]. The sad thing is, you can't file a bug to say so. "Hey Linus, I have some crashes sometimes when under heavy load. Sorry, no logs..."

Edit: Although I strongly suspect the problem is somewhere in the IO scheduler and the way it handles load... (on single CPU machines)

IvanMajhen · Post by **IvanMajhen** » Sat Jul 28, 2007 10:20 am

Could you add acer_acpi patch in next release? http://www.mail-archive.com/linux-acpi% ... 07820.html
It works great on my laptop, and now i can change brightness via hal and kpowersave.

I'm on -ck based kernel now for some time and fortunately no signs of crash/panic...
If it's a buggy IO scheduler that causes those crashes it must have something to do with CFS cpu scheduler...
But as you said if I told the LKML folks about that they had ordered using some serial line console to connect and debug or some RTFM stuff

I tought about debugging it with kexec but I don't have spare time to offer for now...
Not that I would discard CFS totaly it gets better with every release... sometimes it's even more responsive than SD... But...
I am not going to sacrifice my data for testing purposes right now... And I'm sick of doing fsck thrice a day after my box gets stone cold...
A few more and I'm going back to... say 2.6.17-emission8 kernel... 'cause even 2.6.22 vanilla is for me to experimental...

Hi Waninkoko

well, sorry to trouble you, but X still freezes. how I can help you with diagnostic? I don't finde any error messages or logfiles. After X froze I still can go to the console AND I still can kill X with <Ctrl><Alt><Backspace>. The content of the windows still refreshs. But I can't type nor click .

I really like to help because your patchset ist really great. by the way: kamikaze3 feels more smooth than kamikaze4 does. On the other side kamikaze4 doesn't skip sound when I move windows, but kamikaze3 does sometimes.

best regards
are

Linux-PHC Options seems to be missing (tested on i386 and x86_64)
