Justin,

We are looking into this issue and should get back to you soon.

The lock/unlock() kernel calls were not added by me but were part of a
series of 'BKL pushdown' patches added by someone to all drivers with
an ioctl interface.  If you think those might be related to your
issue, you could try
removing those 2 lines of code and recompiling.

If you haven't already, please email you kernel .config files for both
the working kernel and non working kernel to the 3ware/LSI support
people you are in contact with.

Thanks.

-Adam
