Linville" <linville@...driver.com>, maximilian attems <max@...o.at> Subject: [147/197] b43: Remove reset after fatal DMA error 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Larry Finger <Larry.Finger@...inger.net> commit 214ac9a4ead6cb254451c09d9c8234a76693feb1 upstream. 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 <Larry.Finger@...inger.net> Signed-off-by: John W.
