This is clearly the cause of all the trouble. The driver is a bit
opaque at this point, but it looks like an LQI phase error occurs
because of a phase mismatch during L_Q Information Units (These are a
requirement for fast-160 data transfers).
I think this is a strong indicator of bus instability ... could you try
falling back to fast-80 and turning off IU transfers (You'll probably
either have to use the card bios or dig around in the aic79xx driver for
the options).
