Cannot run kernel above version 2.6.8 on P4

I'm running kernel 2.6.8 on an Intel P4 3ghz (IBM ThinkCentre).
 

 uname -a
 Linux f-desk 2.6.8-gentoo-r3 #2 Wed Mar 16 23:29:37 EST 2005 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GenuineIntel GNU/Linux
 
 It works fine but if I try to upgrade to either of these kernels:
 linux-2.6.10-gentoo-r6
 linux-2.6.11-gentoo-r4
 
 My computer starts slowing down, and exhibiting general flaky behaviour, until it is basically frozen. It seems to happen especially when doing a large emerge or compile or when running qemu (an x86 emulator). I can't recover, once it happens, without a reboot.
 
 Is anyone else having these problems? Is there an issue with the p4 and these kernels? Is it possible it's a hardware problem that only shows up in > 2.6.8 kernels? If it is hardware does anyone have a way to test?
 
 Any insight appreciated.
 
 Thanks,
 ajnabi

You may want to post a pointer question in the Linux TA, since your hardware is probably okay (a previous kernel version works), and this problem is very Linux-specific.

Callandor,

Good idea,
Thanks

Hmm,  How do I do that.  Do I just put a link in to this question?  I have to assign points. Will this mess up the point distribution?

How do you know if your security is working?

Protecting your business doesn’t have to mean sifting through endless alerts and notifications. With WatchGuard Total Security Suite, you can feel confident that your business is secure, meaning you can get back to the things that have been sitting on your to-do list.

Just post a 20-point question in the Linux TA with a link to this question, directing them to post here.  When you get a solution, delete the 20-point question in the Linux TA.

are you using the same kern conf from previous kernel build? does this p4 do hyperthreading? I am not familiar enough with gentoo to give you any good info on what to check for w/r/t distro-specific things, but if the prob goes away when you revert to older kernel, i would assume there's either a bad driver or option in your kern config that is causing this. I would recommend you rebuild your kernel with absolute minimal options; you may also want to post this to a gentoo list/forum with any logs you can dig up (right before the freezing occurs).

Thanks dpiniella,

>does this p4 do hyperthreading?

I believe I have hyperthreading in this p4.  I have tried different hyperthreading optimizations.

> I would recommend you rebuild your kernel with absolute minimal options;

I have also tried minimal options while rebuilding the kernel.  Of course I could have missed something.  I will try using the config file from the older kernel.  

>are you using the same kern conf from previous kernel build?

I didn't know that could be done.  I guess it ignores obsolete config settings?  I will try that.

any changes in the config (new questions etc) will get asked and things that are identical will not (generally).

dpiniella,

Ahh Ok! I am going to recompile with my 2.6.8 config and see what happens. I'll post results.

Thank you,

Due to a project being unexpectedly thrust upon me I have not been able to put time into this kernel issue and probably won't for a good month or more. If anyone has interest in seeing the results and continuing this thread I will gladly post results when I do get time for it. Otherwise I will close the question and split the points.

Thanks all.
