Bad CPUs / Bad luck / bad MB or Bad FreeBSD ?

[Mike Tancsa]

I have been testing out a new MB chipset as well as some of the newer 
Celeron CPUs.  Dmesg shows it as

Dec  7 19:51:47 sata48 /kernel: CPU: Intel(R) Celeron(R) CPU 2.50GHz 
(2500.43-MHz 686-class CPU)
Dec  7 19:51:47 sata48 /kernel: Origin = "GenuineIntel"  Id = 
0xf29  Stepping = 9
Dec  7 19:51:47 sata48 /kernel: 
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUS
H,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>

So far we have tested 2 new CPUs, and both seem bad in that I get random 
crashes when doing a buildworld.  Dont know if its some strange motherboard 
interaction or not, but the same MB works great with a plain old P4.

Timecounter "i8254"  frequency 1193182 Hz
CPU: Intel(R) Pentium(R) 4 CPU 2.66GHz (2667.13-MHz 686-class CPU)
   Origin = "GenuineIntel"  Id = 0xf29  Stepping = 9
   Features=0xbfebfbff<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,HTT,TM,PBE>

It would seem like its just a bad luck issue with 2 CPUs both "bad" or 
perhaps the motherboard not liking these Celerons?  But its the first time 
I have ever gotten 2 bad CPUs in a row.  Just to rule out the unlikely, has 
anyone run a celeron with Id = 0xf29 on FreeBSD 4.x with good results 
?   The motherboard is an 865 with integrated em nic and sata controller
