RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific
checking code. This causes two problems. Firstly if SCSI == n just
defining scsi_is_sdev_device() to return false might not be enough to
prevent gcc from emitting the code (and thus referring to undefined
symbols), so this needs surrounding with an ifdef. Secondly, using
scsi_is_sdev_device() when SCSI is either y or m gives a subtle

This patch adds a reboot notifier that will issue a shutdown prepare command

fail over and log and error.

sata_via: Delay on vt6420 when starting ATAPI DMA write
When writing a disc on certain lite-on dvd-writers (also rebadged
as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends
up in the datastream and on the disc, causing silent corruption.
Delaying between sending the CDB and starting DMA seems to
prevent this.
I do not know if there are burners that do not suffer from
this, but the patch should be safe for those as well.

I have a Delkin Devices compact flash card that isn't being recognized using the

The card is recognized and works with the deprecated ATA drivers.
The error I am seeing is:
ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)
I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.
