PROBLEM: ide-cs - error when turning disk off

[Adam Wysocki <gophi-lkml@chmurka.net>]

As suggested in REPORTING-BUGS:

[1.] ide-cs - error when turning disk off

[2.] I have a PCMCIA CF card reader handled by the ide-cs module. It 
has a Kingston CF card plugged in. When I turn off my notebook, just 
after "Will now halt." message, I get:

hdc: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: task_no_data_intr: error=0x04 { DriveStatusError }
ide: failed opcode was: 0xe7
Shutdown: hdc

[3.] Keywords: ide-cs, pcmcia, taskfile

And in dmesg, after plugging it in:

[8.6.] SCSI information: Seems irrelevant.

[8.7.] Other information that might be relevant to the problem:

Doing hdparm -Y /dev/hdc does not reproduce this error, it occurs only 
when turning PC off.

Thanks.
