Hi,
My machine, a Duron 800 Sony VAIO laptop, paniced while running buildworld
under 4.5-PRERELEASE cvsupped 14:00 on 08/01/2002. I'm no kernel debugger
and freely admit i have no idea what to do, but hopefully the gdb output
below will help somebody. kernel core file can be uploaded somewhere if
specific people want to see it.
I was running buildworld, with /usr/src and /usr/obj on seperate
partitions, both with softupdates on. I have the problematic VIA
southbridge. I was building world, then suspended it (ctrl-z) before
suspending the laptop with 'apm -z'. Later, woke it up, and about 20
seconds later resumed the build. Two or three more files were compiled
before the kernel panic occured.
I've attached a dmesg and the gdb output, as well as the output from
'pciconf -r -b pci0:0:0 0x0 0xff', in case it is some problem with the via
chipset. The laptop has run stable except for this one panic and has
compiled world several times. the debug kernel and vmcore are available
for download if someone wants to look at them. Email me privately for the
url.
Thanks!
gavin
