After upgrading to RELENG_7, I got a page fault trap in ffs_softdep.c:add_to_worklist() while running cvsup. I assume it only occurs during heavy disk IO. Since it's RELENG_7, INVARIANTS is not on. Looking at the surrounding code, it appears the trap is a side effect of a bug somewhere else (possibly an invalid workitem list). If it happens again, I'll try to get a better bug report in. Just curious if anyone has seen this. -- Nate
