[olug] Need guru help

[Carl Lundstedt]

Hey OLUG & HLUG,
Ok, so I've set up a server for my research group at UNL.  It's a dual
PIII 1GhZ machine on a Tyan motherboard.  I had to recompile the kernel
to get the built in promise RAID controller to at least act like an ide
controller.  (I used Mandrake 8.2 as a launching point since I'm
familiar with it's server setups. RH 7.3 gave me fits.)

With the custom kernel build I get the following errors (warnings?)
intermittently (shows up in /var/log/messages)

Jun 17 08:28:06 crop kernel: APIC error on CPU0: 02(04)
Jun 17 08:28:06 crop kernel: APIC error on CPU1: 04(08)

I didn't see these with with the stock SMP kernel.  I can change the
frequency by monkeying with some kernel settings before recompile (these
errors were coming in every 15 seconds), but I'm not sure (now) what
settings helped curb them (I may have just shut down the APIC
reporting.)


a) Do I need to worry about these?  I've seen on the web that these
don't mean anything if the system is stable (but I have had some
weirdness with this machine, in particular lost interrupts and lost
ethernet cards, but these have cleared up since the last
re-config/recompile).  What do these errors mean?

b) What can I do about this?

c) Why wouldn't these show up in the stock smp kernel?

d) other thoughts?

If it would help, I can send a partial .config for the kernel.
