Subjectfrequent and severe irq timeout with 2.2.14pre13
I upgraded to 2.2.14pre13 and error of irq timeout got
more frequent and severe.

My /var/log/messages is filled with the message as follows:
(I install linux on /dev/hdb)

Dec 15 11:55:07 alfonz kernel: hdb: irq timeout: status=0xd0 { Busy }

When the error happens no disk access is possible.

When I used pre11, it could be decreased by setting

hdparm -X65 /dev/hdb

But now I must set -X12 to make it stable.

The resoult of hdparm -t decreased from about 7.5M/sec
to about 5.8M/sec.

Hardware environment is,

M/B GA-586S2(SiS5582)
/dev/hda Maxtor 84320D4 (Windows 95)
/dev/hdb Maxtor 92040U6 (Linux)

I remember pre9 or older versions has no such problem.
