[illumos-Developer] WEBREV: 434 kernel crash dump on comstar iscsit

[Garrett D'Amore]

  I remember this webrev now. :-)

Can you describe your testing?  Also, a mail_msg from a nightly build 
and output from hg pbchk would be good.

I would like to get one more reviewer on this, if at all possible.
