Re: NetBSD-current on amd64 with Dell PERC 4e/Di hangs under load
I tried building a kernel with LOCKDEBUG, but that hung about halfway
through the /etc/rc.d/ scripts, so I gave up on it. I've just managed
to get a proper core dump from a hang. Didn't write down the backtraces
for the various CPUs, but one was doing disk I/O, one was in pf handling
a fragment (and calling kernel_lock()), one was in ipmi (again, calling
kernel_lock(), I think), and the final one was servicing some interrupt.
If there's anything I ought to pull from the dump, please let me know!
Here's what it looks like (there's a full build running):
barsoom# /usr/src/usr.sbin/crash/obj.amd64/crash -M netbsd.27.core -N /netbsd
Crash version 7.99.4, image version 7.99.4.
System panicked: dump forced via kernel debugger
Backtrace from time of crash is available.
