[hsflinux] unable to handle kernel NULL pointer dereference...

[Michael Landon - IBN]

After some more testing, I've come across another OOPS statement.  I'm using
the latest hsf drivers (5.03.03.L3mbsibeta02072100k2.4.18_3) w/ RH 7.3.
Looking around the system after the statement below occurs, the
[cnxthsf_mdmthrd] process is no longer running.
