From e11db063d86d0ef9d7903cb463bb542b5d4e9ddd Mon Sep 17 00:00:00 2001 From: Michael De Backer <micdb@skynet.be> Date: Tue, 12 Sep 2006 20:35:53 -0700 Subject: [PATCH] [PATCH] alim15x3.c: M5229 (rev c8) support for DMA cd-writer Configuration bits are not set properly for DMA on some chipset revisions. It has already been corrected for M5229 (rev c7) but not for M5229 (rev c8). This leads to the bug described at http://bugzilla.kernel.org/show_bug.cgi?id=5786 (lost interrupt + ide bus hangs).
