This is how the MacOS does it, at least prior to MacOS X. If the CD-ROM
is external and powered-down after the MacOS boots, the Mac then hangs
periodically trying to ping it. Really screws up performance. :)

cheaper.

So I thought I'd forward the results to current, for what it's worth.
The biggest (non)surprise is how big a difference softupdates makes.
Nice!

Forgot to mention - SMP makes no difference to the crash. I've turned
it off for now to simplify debugging. Just vinum+raid5+softupdates
seems to be enough.

dates the raid5
volume seems happy, with and without async. It seems likely to be some
odd interaction between the raid5 code and softupdates, since the
simpler mirror/striping seems to work fine with it.
Ring any bells for anyone?

Wow - I'm impressed! You really know your kernel debugging! :) It is a
null-pointer dereference that's crashing it. Here's the gdb stack

I'm building a new kernel with gdb serial debug and will try to extract
more info from it if possible. First I have to wait for the array to
come back from the dead. :)
In the meantime, appended is my kernel's config file.

There are no apparent SCSI errors, and access to the raid10 volume plus
a single vanilla FFS filesystem on the extra SCSI drive are fine.
Thoughts? Thanks!

Then why bother having rc.conf in the first place? Just wire in all
the defaults straight into /etc/rc and leave rc.conf strictly for
overriding the defaults only, and eliminate rc.conf.* entirely.
