Yes, I've seen this once on reboot on i386, NetBSD 1.5E (-current) kernel.
IIRC it was classic trap()-type panic. It happened when
the final sync started, before any info about synced buffers was
printed. I'm not using MFS or any other "special" filesystem,
just FFS & NTFS.

Does the proclist walking in suspendsched() need to be guarded by
proclist_(un)lock_write() ?
