From 214ac9a4ead6cb254451c09d9c8234a76693feb1 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Wed, 9 Dec 2009 13:25:56 -0600 Subject: [PATCH] b43: Remove reset after fatal DMA error As shown in Kernel Bugzilla #14761, doing a controller restart after a fatal DMA error does not accomplish anything other than consume the CPU on an affected system. Accordingly, substitute a meaningful message for the restart. Signed-off-by: Larry Finger Cc: Stable [2.6.32] Signed-off-by: John W.
