From 3f7086978fc0193eff24a77d8b57ac4debc088fa Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Tue, 4 Sep 2007 14:14:20 -0500 Subject: [PATCH] bcm43xx: Fix cancellation of work queue crashes A crash upon booting that is caused by bcm43xx has been reported [1] and found to be due to a work queue being reinitialized while work on that queue is still pending. This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced.
