Is this reproducible?

A patch went into ac3 which attempts to address qlogicisp problems on
Alpha. It originated from the nether regions deep inside Compaq,
original source unknown. There is a -extraordinarily slight-
possibility this patch (which simply adds "mb()") causes problems.
However, it is more likely that the patch is harmless but also useless,
not fixing the real problem.

Other questions - is your machine SMP? How much RAM?
