Hello,

we've got some new machines, which are Intel Xeon "Nocona".

These processors are supposed to be similar to the Opteron ones,
with the support for 64 and 32 bits instructions.
By the way, the /proc/cpuinfo for these machines (installed with
SL in 3.02) gives
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm lm
The last one is for "long mode" with is supposed to be be the
32+64 bits mode.

I manage to install both a SL 3.02 and a SL 3.03 in 32 bits for
these machines, but the 64 bits install failed.
I use the x86_64 scheme for that, all all is fine (PXE boot
on the x86_64 boot kernel, anaconda installation...) until the
machine reboots.
At this point the kernel starts to load and crashes after a
'kernel panic'. The only message I can see is a dump of the
execution stack...

Does someone met the same problem ? Is it the good arch
to use (x86_64) ?
It is not really important as they are used in 32 bits at this
time, but I don't like that :o)

Thank.
