Date: Thu, 19 Aug 2010 14:55:26 -0400 From: Patrick McLean <patrick@....mcgill.ca> To: bridge@...ts.linux-foundation.org CC: linux-kernel@...r.kernel.org, netdev@...r.kernel.org, Herbert Xu <herbert@...dor.apana.org.au>, Jan Binder <jan@....mcgill.ca> Subject: [Bug #16572][REGRESSION, bisected] random panics in bridging on 2.6.34+ Hi, I am getting random panics with KVM/bridging on 2.6.34+ (including latest git as of this morning). There is a screenshot of the panic message in bugzilla at https://bugzilla.kernel.org/show_bug.cgi?id=16572 It seems to happen when I have KVM virtual machines running with bridging mode, most often when any of the virtual machines talk to the network, or sometimes when they are brought up or down. I bisected it down to this commit: commit 68b7c895be336b19f4c38d7cb500132fabba0afd Author: Herbert Xu <herbert@...dor.apana.org.au> Date: Sat Feb 27 19:41:40 2010 +0000 bridge: Allow tail-call on br_pass_frame_up This patch allows tail-call on the call to br_pass_frame_up in br_handle_frame_finish. This is now possible because of the previous patch to call br_pass_frame_up last. Signed-off-by: Herbert Xu <herbert@...dor.apana.org.au> Signed-off-by: David S.
