unexpected interrupt at standby

[matthschulz <matthschulz@gmx.net>]

When i put my old Compaq Contura 410 into standby with 
>apm -S
then i get following message:
>ide0: unexpected interrupt, status=0x80, count=1

Then i left the copmuter unattended and got the following:
>ide0: unexpected interrupt, status=0x80, count=2
apm: an event queue overflowed
hda: status timeout: status=0x80 { Busy }
hda: drive not ready for command
ide0: reset: success

dmesg gives me following:

Kernel 2.2.13 with builtin apm, no problems under OS/2.

Any ideas?

Thanks Matth
