I have a system with an "AMD64 Phenom 9500" quad core cpu, 4GB RAM,

I tried stock debian etch kernel (Debian 2.6.18.dfsg.1-18etch1),

froze with no message, debian etch backport kernel same, and then
Debian 2.6.24-4 from unstable and I got some messages: machine
is not frozen but some userland processes are (ps says "Dl" state
with child in "Zs" state) and "events/3" is taking 100% cpu
according to top:
18 root 15 -5 0 0 0 R 100 0.0 74:59.46
events/3
Got to the same state with ubuntu hardy 2.6.24-8-server kernel. All
kernels are untainted, no X running anyway.
It takes a few hours of doing some stuff, in my case bootstraping or
testing GCC at -j 4, and then the problem happens.
backtrace in /var/log/messages after a few hours of stressing the
machine with compilations, see below. The given process
was stuck and unkillable.
Any idea on what to do/try?
I changed motherboard and went for a (way cheaper but older) ASUS M2A-VM
with is based on the AMD 690G chipset with the exact same
kernel/phenom/memory/disk/box and installed the latest vendor BIOS
(1604). It took longer (25 hours) to get a stuck and unkillable process
but it did happen, but I got nothing in /var/log/kern.log this time.
In order to rule out a motherboard or memory issue I bought an Athlon X2
4400+ EE and put in replacement of the phenom with the exact same
kenel/memory/disk/box and my stress test has been running for 72 hours
without any issue so far.
So in the end it seems to be a problem specific to phenom 9500 with the
linux kernel.
Did anyone succeed in getting a stable linux box based on a phenom 9500
processor ? "Stable" defined as being able to survive a few days
compiling at -j4 (this is for the GCC compile farm after all :).
If so I'm interested by the exact motherboard/bios version/kernel
version/distro used.
As proposed in my first email, ssh root access is possible to my machine
(with either motherboard).
Thanks in advance,
Laurent
