From d3ae33efb8e2f277f9007eb060c9d0b91ab38ae1 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 2 Jun 2009 12:34:31 +0100 Subject: pata_netcell: LBA48 force identify bits correct This matches Bartlomiej's patch for ide_pci_generic: c339dfdd65b52bfd947ab29d1210314a2f6d622d In the libata case netcell has its own mini driver. I suspect this fix is actually only needed for some firmware revs but it does no harm either way.
