Hi,
While testing the FC pass thru support I am constantly hitting a
kernel crash when BSG request times out.
I took the latest FC pass thru patches from James Smart from
http://marc.info/?l=linux-scsi&m=123436574018579&w=2. and on top of it
applied Boaz patches from
http://markmail.org/search/?q=FC+pass-through+support+&x=0&y=0#query:FC
%20passthrough%20support%20from%3A%22Boaz%20Harrosh%22+page:2+mid:ke4lj4cg5ftc6nsc+state:results
Is there any additional patches I am missing?
Thanks,
Giridhar.M.B
