NetBSD/amd64 4.99.48 hangs


I having weird hangs on my test host, the host responds to ping but everything else is frozen. I quite often can trigger this my running "cvs update -dPA" at the same time on /usr/src, /usr/pkgsrc and /usr/pkgsrc/wip. The update usually stops at the end, most likely during the purge (-P) phase so this might be disk related.

Here're the details of my host:

Next I'll try with MULTIPROCESSOR disabled.

PS. Is kernel debugger supposed to work? I can't enter it with Ctrl+Alt+Esc...
