Subject: Re: -current MP kernel hangs

Well, just to give a little more info on this...

At least one other person indicated that they were having no problems
with the GENERIC.MP kernel.  Mine happens to be a custom kernel, with
only real stuff in the config file, and everything nailed down.  The
actual kernel config is at the end of this mail...

Anyway, I suspect that something is broken WRT interaction with the
machine's BIOS.  This is on a ASUS CUV4X-D "Dual Socket-370 Motherboard"
with "Apollo Pro133A Chipset" (according to the accompanying User's
Manual!).  What leads me to believe that this is BIOS-related is that,
every boot that follows a hang, the BIOS drops me into a menu asking me
to select my boot device.  Normally, it just "does the right thing" by
booting my IDE drive, but once the machine has hung, I have to answer
this menu!

When it hangs, there's absolutely nothing on the console, and there's
absolutely no response to anything.  If I have top(1) running, the
display (including the clock) freezes totally.  No keyboard interrupts
seem to get through, and the network seems to be dead, too (no response
to ping).

I'm stumped.  For now, I've gone back to my 1.5ZA kernel, which is
running just fine (even with the 1.5ZC userland!).

Anyone got a clue-by-four with which you can whack me upside the head?
:)
