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?
