Subject: [PATCH] libata: Add multi-count transfer debugging
Date: Wed, 06 May 2009 15:45:18 +0200 [thread overview]
Message-ID: <4A01946E.1020300@gmx.net> (raw)
On my Asus M2A-VM (SB600) board, the SATA disks use multi-count
transfers only with some BIOS variants.
Dumping the relevant config words helps debugging a lot.
