Matthew  is not alone with this problem.  I have it too.  Its not new here.  Its
been happening as long as I have had gentoo amd64 installed.  It can be hard
to reproduce but eventually, when 32 bit apps are used, my box bricks.  There is
nothing in the logs (nor on a serial console) - the box just freezes.  

My kernel is _not_ tainted.  The kernel is currently 2.6.23-gentoo-r5-crc with 
the latest cfs backport applied; it does not seem to be critical though as it has
happen with all kernels I have tried (mm, linux and gentoo varients).  

The processor is:

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 4
model name      : AMD Athlon(tm) 64 Processor 2800+
stepping        : 10
cpu MHz         : 1808.802
cache size      : 512 KB
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow rep_good
bogomips        : 3620.77
TLB size        : 1024 4K pages
clflush size    : 64
cache_alignment : 64
address sizes   : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp

I asked about this lkml before and was told it was probably a cpu/hardware issue...  Its 
interesting that Matthew is also running gentoo.

Thanks,
Ed Tomlinson
