Hi,
I have an ABIT BP6 mobo with 2 celeron 400 running redhat 7.1 with 2.4.3
SMP (from kernel.org not from redhat)
it works well.
But when i try to update my kernel, i always get a lockups in few
minutes. sometimes kernel just freeze when booting.
I have tried other kernel such as 2.4.5, 2.4.6 and 2.4.7 and I always
get the same result.
but if i compile a non SMP kernel the box is stable.
Is it a know problem ?
are there a work around ?
thanks

before you blame smp, try the usual bp6 stuff:
* bigger/better power supply
* better cooling
* boot with 'noapic' on commandline
search a linux-kernel archive (http://marc.theaimsgroup.com)
for more info. these boards seem to be a bit of a lucky dip. some
never have any problems, others have heaps. i have a vague memory of
someone mentioning flaky caps on some revisions... also are you using
the onboard ata66 controller? there's been a fair few reports of
trouble with those, not sure if it was fixed/hacked-around or not.
best of luck,
j.

350 W should be enough (just 1 HD and 1 DVD + mobo ) ?

I have 2 big fan :)
cpu temp is typically 35 °C

thank for response

Lots of apic errors imply problems on the link between the processors and
io controller. A few is basically ok (there is a checksum) but a huge number
and one day it'll checksum a bad frame ok and you are history
There is also a problem with Linus tree where apic errors causing event
replays where the erroring component was not the CPUs can cause crashes.
That is fixed in -ac.

So I think it's ok for my 2.4.3, I just have about 5 ~ 10 apic error by
hour

I have tried 2.4.9-ac4 and i still have a freeze in few minutes, but
when i configured it with noapic all seem ok, I use the box 3 hours
without freeze
