From 4e57c517b3cbaceb7438eeec879ca129fc17442c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 16 Jul 2007 14:29:41 +0900 Subject: libata: schedule probing after SError access failure during autopsy 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.
