- *	After the IDENTIFY [PACKET] DEVICE step is complete, and a

- *	We apply two errata fixups which are specific to Silicon Image,
- *	a Seagate and a Maxtor fixup.
- *
- *	For certain Seagate devices, we must limit the maximum sectors
- *	to under 8K.
- *
- *	For certain Maxtor devices, we must not program the drive
- *	beyond udma5.
- *
- *	Both fixups are unfairly pessimistic.  As soon as I get more
- *	information on these errata, I will create a more exhaustive
- *	list, and apply the fixups to only the specific
- *	devices/hosts/firmwares that need it.
- *
- *	20040111 - Seagate drives affected by the Mod15Write bug are blacklisted
- *	The Maxtor quirk is in the blacklist, but I'm keeping the original
- *	pessimistic fix for the following reasons...
- *	- There seems to be less info on it, only one device gleaned off the
- *	Windows	driver, maybe only one is affected.  More info would be greatly
- *	appreciated.
- *	- But then again UDMA5 is hardly anything to complain about
