Adaptec 2940U2W and new 2.110 bios

[Michael Nelson]

I should have known to leave well enough alone, but...

My 2940U2W has been working fine.  No problems.  No timeouts.  Yesterday I
downloaded the latest bios for it from adaptec and installed it (u2w2110.exe).

Since installing it, I get timeout errors during boot.  Sometimes it times
out and resets successfully, other times it panics.  Here are some messages
from a successful boot:

Note that I have also tried with the no_reset option and it's just as flaky
either way.  Once it finds that IBM drive and gets it reset, the system is
OK, no more timeout problems, but it's about a 75% chance it won't make it
through BOOT at all without panicing.

The same hardware boots fine with the 2.2.2 kernel with the 5.1.10 aic driver,
and this hardware also worked fine with 2.2.6 and the 5.1.15 driver UNTIL
the card's bios was updated yesterday.  The previous adaptec bios was 2.10.
