Hi,

One machine regularly crashes.  

Linux version 2.2.16-3 (root@porky.devel.redhat.com) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Mon Jun 19 19:11:44 EDT 2000

Another one, I don't really know, but I was comparing /proc/cpuinfo on
these two machines as they are supposed to have the same CPU: 


/home/wolff> cat /proc/version /proc/cpuinfo
Linux version 2.4.3 (wolff@cave) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #52 Fri Apr 6 14:43:38 MEST 2001

bogomips        : 1101.00

/home/wolff> 


Everything is exactly the same, except for the "cpuid level". Once the
cpu family and model are the same, I'd expect the cpuid level to be
the same too. In this case even the stepping is the same, so how can
the cpuid level differ? 

Maybe this is a reporting difference between 2.4.3 and 2.2.16????

Anybody care to shed some light on this?

				Roger.
