Hi
On my system (2.6.23-rc9) I have Serial-ATA DVD/RW drive connected
to sata_sil controller. Sometimes when there is a problem with CD
or DVD disk controller shutdowns drive:

[53650.042632] ata6.00: detaching (SCSI 6:0:0:0)
Is there a way to re-enable ata6.00 in other way then power down/power up
whole machine? Looks like reboot is not a way to get it working again.
Drive is found as:

[ 97.012480] ata6.00: ATAPI: TSSTcorpCD/DVDW SH-S183A, SB02, max UDMA/33

[ 97.169126] ata6.00: configured for UDMA/33
