Aiee with NCR53C875

I keep getting Aiee:s with the new kernels. The booting is OK, and
after a short time (just a few ls, sometimes some minute) I get SCSI
reset, and then it use to keep resetting. (Sounds similar to the
problem with aha:s). After some resets it usuallt starts to aiee, an
there is nothing to do but reset (MagSysRq boot works, but not always the
sync and umount.) I have a Microstar 6109 PII, with 1 ultrawide disk
and 3 old small ones.

The 2.0.35 kernel works OK.

PS The problem started when I mover the computer to a different
room...
