:===
I have occassionally seen this failure when setting vfs.vmiodirenable
to 1. I have not seen it otherwise.
Please upgrade your system to the latest ffs_softdep.c, vers 1.47. This
will fix a number of other problems but may not fix this one.
If you can reproduce this bug reliably w/ the latest ffs_softdep.c then
we may have a chance of finding it.

This is new to me too.
Any chance you can get a kernel core dump on these machines instead
of just rebooting? And have a debug kernel for them?
:Both machines are of -current, Dec 26 vintage. These machines died
:building -current packages. (Gee, sounds like real heroes.) These
:crashes usually result in fsck -p failing during subsequent reboot.

Yes, the fsck thingy happens to me too though if this is a Dec 26
kernel you should definitely update it -- I seem to recall something
related to fsck being fixed around that time frame and there was a
softupdates fix after that time frame for a bug occuring before the
time frame committed as well (separate from the current spate of
softupdates issues).
