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
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:

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.
