Hi, all.

I took another run at getting my SS10 up to speed today. It's currently
running 1.4X and is rock solid. Whenever I try a 1.4Y kernel, I start
seeing all sorts of core dumping.

Does anyone have any thoughts regarding this? I have core dumps galore,
but I'm not quite sure how to pick them apart yet.

PS: This core dumping seems completely orthogonal to:

* The presence or absence of INET6.
* The presence or absense of softdep and softdep-enabled filesystems.
* The presence or absense of update(8) with frequent syncs.

*Most* of the time, /etc/rc.d/network start in single-user mode will not
dump core, whereas 100% of the time the same thing during multi-user boot
*will* dump core. (Specifically, an instance of /bin/sh that ends up
driving ifconfig, I believe, dumps core, leaving the system without
networking resources.)

Since the box mostly exists to track -current and play with new (to me,
anyway) technology, I feel silly leaving it at 1.4X, so any ideas with
regard to diagnostics are welcome. So far, the only thing I've thought
of involves setting it up to netboot, thus isolating the possibility of
some kind of evil interaction with the disks or SCSI controller. I'll
try this this weekend.
