Hi,
while using vanilla 3.10.44 with drbd on top of a md raid1.
I'm pretty often hitting the followin kernel bug.
It reminds me of:

In case of of error, the bnx2fc_cmd_mgr_alloc() function will call
the bnx2fc_cmd_mgr_free() to perform the cleanup.
The problem is that in one case the latter may try to scan
some not-yet initialized lists, resulting in a kernel panic.
This patch prevents this from happening by freeing the lists

During hibernation, the HBA firmware may lose power and forget the device
id info. This causes the HBA to reject IO upon resume. The fix is
to call the libsas power management routines to make the domain device
forgetful.
This fixes bug 76681: https://bugzilla.kernel.org/
While trying to bisect some problems which were introduced sometime
between 3.15 and 3.16-rc1 (specifically, (1) reads to a block device
at offset 262144 * 4k are failing with a short read, and (2) block
device reads are sometimes causing the entire kernel to hang), the
following BUG got hit.
