H A Dlibata-eh.cdiff 771b8dad9653d2659e0ffcc237184cb16c317788 Tue Mar 13 11:20:51 CDT 2007 Tejun Heo <htejun@gmail.com> libata: hardreset on SERR_INTERNAL

There was a rare report where SB600 reported SERR_INTERNAL and SRST
couldn't get it out of the failure mode. Hardreset on SERR_INTERNAL.
As the problem is intermittent, whether this fixes the problem or not
hasn't been verified yet, but hardresetting the channel on internal
error is a good idea anyway.
