Re: 4.0-CURRENT SMP crash with vinum raid-5 and softupdates

[Parag Patel]

Just to let everyone know, Greg's going to be out-of-town for a little
while and won't be able to continue debugging.  I'm taking a crack at it
again.

So far, it seems to be a combination of softupdates+vinum+raid5 that
triggers the bug, whatever it is.  If I turn off softupdates 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?
