Hi all,
Previous kernel I was running on a test SAN was 9-STABLE from Jan 24th.
Sorry, no commit # -- didn't have svn on the machine back then.
Today I built r231282 because it had an interesting fix in it:
r231141 | mm | 2012-02-07 11:57:33 -0600 (Tue, 07 Feb 2012) | 25 lines
MFC r230514:

After booting into this kernel iSCSI was hosed. None of the ESXi servers
looking at it could do any I/O at all. Weird errors in the istgt log, too:

I didn't see any other commits between that could cause this, but can
anyone else confirm? After rebooting into the Jan 24th kernel everything
went back to normal...
Thanks,
Mark
