regarding sata_sis kernel freeze when BIOS is not updated to support LBA48

Hello, Uwe Koziolek, Jeff.

Alexey Fisher has filed bug #7314 and resolved it by himself. :-)

http://bugzilla.kernel.org/show_bug.cgi?id=7314

The problem seems that the BIOS isn't updated to support LBA48 but libata doesn't know about it and issue LBA48 commands anyway. I suppose there's a way to detect this mechanism. We can either force LBA28 mode or at least print warning message urging the user to upgrade BIOS if such condition is detected.

Any ideas on how to detect this?

Thanks.
