+Subject: ahci.c: walkaround for SB600 SATA internal error issue
+X-Git-Tag: v2.6.21~206^2~3

http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=55a61604cd1354e1783364e1c901034f2f474b7d

+ahci.c: walkaround for SB600 SATA internal error issue
+
+ There is a HW issue in ATI SB600 SATA that PxSERR.E should not be
+set on some conditions, for example, when there is no media in SATA
+CD/DVD drive or media is not ready, AHCI controller fails to execute
+ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA
+controller sets PxSERR.E at the
+same time, which is not necessary.
+ This patch is just to ignore the INTERNAL ERROR in such case.
+Without this patch, ahci error handler will report many errors as
+below:
+ ----------- cut from dmesg -----------

+ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
