It seems that I have still SCSI-Lockups. I can force lockups by reading
some 50MB from by /dev/sda1. There are no messages in the logs. There is a
message on the console, reading "(date)(hostname) kernel: (scsi0:0:0)
Target busy)".
Lockups occured with 2.1.88, 2.1.89 and 2.1.90 and, if I remember
correctly, also with 2.0.3[23], each with SMP on a Dual Pentium. Some
other data:

------------------
With that "target busy" message, I suspect the aic-7880 module is the
culprit.
What could I check? Are there any patches I could try?
