From 26b6da6b7829dc7cf5d21e854564be90c7928323 Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Wed, 27 Jun 2012 10:36:27 +0200 Subject: iwlegacy: print how long queue was actually stuck Every now and then, after resuming from suspend, the iwlegacy driver prints iwl4965 0000:03:00.0: Queue 2 stuck for 2000 ms. iwl4965 0000:03:00.0: On demand firmware reload I have no idea what causes these errors. But the code currently uses wd_timeout in the first error. wd_timeout will generally be set at IL_DEF_WD_TIMEOUT (ie, 2000). Perhaps printing for how long the queue was actually stuck can clarify the cause of these errors. Signed-off-by: Paul Bolle Signed-off-by: John W.
