Subject: [PATCH 20/21] libata: schedule probing after SError access failure during autopsy
Date: Mon, 16 Jul 2007 14:29:41 +0900 [thread overview]
Message-ID: <11845637811756-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11845637782629-git-send-email-htejun@gmail.com>
If SError isn't accessible, EH can't tell whether hotplug has happened
or not. Report SError read failure with AC_ERR_OTHER and schedule
probing with hardreset. This will be mainly useful for PMPs.
