Re: panic in ioapic
I see the exact same problem with dual opteron 8G platform. Try
increasing the kernel stack
I am using NetBSD 4.0_STABLE at a dell 1950 with two dual core CPUs
and 12GB ram. If I use a kernel without any apic everything works
fine. If I use a kernel with enabled apic (one cpu or four cpus)
after some time the kernel gets a panic in Xintr_ioapic_level5
you can find the screenshot at http://suse.uni-leipzig.de/dump.bmp
the error occurs in different processes like ftp, httpd or rsync. but
always the apic funktion is affected.
unfortunaly the debugger does not respond to any input and so I can't
report a full trace.
any idea what the problem can be?
I've set UPAGES to 5 in /usr/src/sys/arch/amd64/include/param.h.
You can also set INTRSTACKSIZE to 8k there as well, but this doesn't
seem to have much effect for me. I mention this because the i386 port
is already set to that value.
We should open up a PR for this.
