Subject: [PATCH #upstream-fixes] libata: fix follow-up SRST failure path
Date: Wed, 08 Jul 2009 12:16:37 +0900 [thread overview]
Message-ID: <4A540F95.70604@kernel.org> (raw)
ata_eh_reset() was missing error return handling after follow-up SRST
allowing EH to continue the normal probing path after reset failure.
This was discovered while testing new WD 2TB drives which take longer
than 10 secs to spin up and cause the first follow-up SRST to time
out.
