Subject: [PATCH 0/2] fix libata-sff and pata_cmd64x to not crash on boot on parisc
Date: Sun, 24 Apr 2011 14:28:34 -0500 [thread overview]
Message-ID: <1303673315.5231.9.camel@mulgrave.site> (raw)
currently libata-sff is completely ignoring the enabled/disabled status
of the interfaces. This is a real problem on parisc because if you
touch a non responding memory area (i.e. a disabled interface) you crash
the box.
Fix by checking the CNTRL bits to see if the port is enabled before
trying to poke it.
