Well, there are two issues here. First, the "something wicked happened"
message is bogus and should not get printed. I have to sit down and
analyze all the bits in the status, because somehow it keeps passing my
filters when it shouldn't.

The second is that while it's somewhat normal to have the FIFO threshold
increased a few times, especially when there is lots of activity on the
PCI bus, the value really shouldn't have to go very high. So maybe you
have a video card or something else that hogs the bus a lot? A Matrox card
runnin XFree4.x, maybe?

Hmm. I'm really unsure of which driver version is in 2.4.6-ac2, but ac3
should have the latest, including all the patches I posted to the list. So
if you could give that kernel a whirl, it would be very useful.

Other things of interest, if ac3 still gives you troubles:

- the speed and the duplex mode reported by the driver (dmesg will have
them, the syslog logs might not)
- whether you are using Adaptec's firmware (converted from their Novell


It is better to keep your mouth shut and be thought a fool,
than to open it and remove all doubt.
