Upgraded to 3.6 today on my dev box and after seeing an FC attached SAN
go down and come back up (due to an expected reboot) I started getting
the following in my logs. It continues even after the array is back and
functioning - I'm seeing:
kernel:[109104.348034] BUG: soft lockup - CPU#6 stuck for 23s!
[kworker/6:0:30692]
repeated on logged in sessions and backtraces like the following (this
is the first). I don't see the same problem under 3.5.
