(Alan please read my note about Screan Of Death)
I had some similar problems - but noapic solved this
(hdparm -t with nosmp option was cousing some hangs - but
this might be some fault of BX chipset itself - all I can tell
is that this happens when the 100Mbps 3c59x card is in my computer
and the ethernet driver is insmoded - some mentioned
some short paragraph for apic.c source code from linux kernel here)
But I'm being still bite sometime by some obscure NFS bug.
Generaly I could see simillat symptoms as you - with uniprocessor
I have no problems with NFS, while in SMP mode sometimes after long
period of inactivity when I start Netscape or some other
huge program (like ddd) the computer hangs - once it happed
6 times in 10 minutes - but usually I could have two or 3 days
uptime
Is there any skilled hacker on this list ??? who could add something
like infamous screen of death from NT to linux - something which will
print location of two SMP locks after the system spends something
like 5 second in them before it will go down -
this should be possible with NMI and switching to text VGA mode.
I'm quite busy with other things just now - so maybe
some other brave person could make this hack come true ??
(I think for most of deadlock states VGA card could be turned to
VGA 80x26 mode for displaing short message)
I know there is ikd - but I don't have serial console to see the
result there for this lock - also I need to run the system
as regular machine so I would suppose that best thing would
be unmodified system with just some NMI watch dog and
in case of failure it would print Ooopses for each processor
and hang the computer
(Also I would say the computer is locked in SMP lock, because
the temperature for processors goes high after sort
period of time (leave the computer locked for a minute
and after reboot see the temperature in BIOS)
In my eyes there is many SMP bugs in Linux - and as BP6 openned
the doors for of SMP computing for pure mortals :) we are hitting them
more offten (of course has some BP6 bugs too)
