Lately since my fresh gentoo install, i've been having a lot of problems
with the kernel locking up at random.
It's not a hard lockup, or a panic crash, it just stops running new
processes, i get a lot of defuncts.. and dosn't let new users log in at all,
sudo/su-ing either.
I've checked everything, even recompiled the kernel few times,
including/excluding genkernel. Tried disabling APIC by passing noapic.
Nothing seems to work.
I'm running it on a AMD 64 Dual-Core 3800+, Asus A8N-SLI Deluxe Mobo,
4 modules of Kingston Hardcore 3 512MB.
NVIDIA 7800 GTX Vidoe Card/ with lastest nvidia-drivers
(Oh and I ran memcheck for 12 hours, nothing came up)
Basicly I tried everything and nothing worked.. and it appears tu run great
on the livecd kernel.. and crashes at genkernel or a manually compiled
kernel.
Any ideas?
(My current non-genkernel config file is attached)

Nothing in the .config seems to jump out and bite me, so a few questions
for more background:
Which kernel version?
Is this a new machine, or a new install on an old machine that used to
work fine?
If it's the second, what was the last known good kernel that ran?
I'd like to see a 'diff -u' between the current config and the last
known good one

Which kernel? Have you tried the latest vanilla release?
Use SysRq-t to see what is happening. Chances are you have a deadlock somewhere.
Cheers,

Its a new install on an old box.. sorry but I don't have the last config

SysRq-t? Sorry can't find it in portage, can you explain please?

I had the same experience, when I turned on the 'DMA engine' option in
the kernel config (from 2.6.18.x)
I disabled it and after it everything are working fine.

Fair enough, let's see where the problem seems to be, anyway.

Yep. If things are going *very* badly then writing to the system log
may be failing. In that case you can switch to a console and use
SysRq-9 then SysRq-t to send the output to console. Check your system
log first though. Much easier to get it from there than copying things
down by hand or photgraphing your screen!
Cheers,
Duane.

That's interesting. I've wondered what that option is since it came out,
as documentation for it is sparse. Not knowing what it is, I've always
left it disabled.

I turned off Preempt Big Kernel Lock earlier today, and haven't had a
deadlock/crash since.
Apparently that solved it.. thanks for the help/support

I have an AMD Athlon 64X2 4200+ and Have the "Preempt Big Kernel Lock"
turned on in my 2.6.19 kernel and have experienced no problems. Don't
know if that helps or hurts but just thought I'd let you know.
