Re: 20041007: LDM situation on bigbird (cont.)

I had another failure about 2 hrs ago, which I just detected 
(coffee-deficiency; should have caught it earlier).  I'm going to move 
the machine back to FC1 this weekend or Monday.  Seems like the best way 
to go for now.

Steve, I found numerous references to APIC and ACPI incompatibilities 
for the 2.6 kernels when using SMP.  Further, there's an interesting 
glitch, now worked around in my case, regarding PS/2 keyboards and mice. 
 I'm really sorry 2.6 isn't working for this, as there are some 
efficiencies implemented in the IP stack that would have helped.


Anne, I'll preserve the iptables stuff you added; do I need to preserve 
any innd config files, or do you want to just re-install?

Tom,

I've not ruled out the possibility of a hardware fault, but backing down 
the software in the face of the number of errors detected seems like the 
next troubleshooting step.  It's faster than getting in a new 
motherboard.  While there's a possibility it might be a fried Xeon, the 
fact that they post and there are no identifiable processor faults 
suggests that's not the vector.  On-MoBo failures are somewhat harder to 
identify, but I'll keep looking.

Thanks, y'all!
