Hi everybody,
this is my first time posting linux-smp mailing list and hope someone could
help me for my problem.
Here at office we are using a RedHat 6.0 distribution (kernel 2.2.5-15 smp)
on a Compaq proliant 5500 server (dual Xeon @ 500 Mhz processor, 512 megs of
RAM, scsi raid controller, intel 10/100 ether card).
We've got a lot of system crashes since installing Smp kernel last november
(at first, we used single processor kernel of the same distribution)
Tipically, the server 'lives' for a couple of days, when several user log
in, suddenly crashes without (apparent) reason.
I read the "Linux SMP HOWTO" and it seems 2.2 kernel should be quite robust
for SMP.
I know about APM problems and APIC settings but could not modify BIOS
settings in the server
What's wrong with it?
Please help me making that server "solid as a rock" !!
I attached last BootMessage.
Thanks in advance
Maurizio Barbaro
