Perplexing problems I have with a new system here. ASUS XG-DLS motherboard
with 2 x Xeon III processors running at 550MHz with 512KB cache. The
motherboard manual advertises that it's suitable for a 550MHz processor,
but didn't have positions for 550MHz. However it was fairly obvious to
work them out.
BIOS says there's 2 processors, but when I tried to boot it for the first
time (Debian 2.1/2.0.36) it locked solid half way into the install. Tried
it again and it locked solid during the FSCK. no caps-lock/num-lock LED's,
etc. Needed a hard reset to unlock it.
I took a processor out and tried again - worked fine. Installation went
OK, built a new kernel (2.2.9 with SMP enabled) and it booted fine on one
processor. Plugged in the 2nd processor and it locked solid again as I
tried to login.
The motherboard has 512MB of ECC memory in it (4 DIMMS) and ECC is enabled
in the bios.
Anyone have any clues or suggestions? I'm going to try fiddling with the
speeds - clock it down to 500 then to 450 to see if that helps. The CPU's
aren't overheating (even though they don't have fans attached they are
barely warm to the touch and I did several kernel compiles with a single
processor installed. (which usually shows up memory problems in other
systems I've built!)
I've attached the output of dmesg and cpuinfo from when it runs with a
single CPU if anyones interested.
Any advice would be appreciated.
