Hi All,
Just got a crash with a linux-4.4-mw kernel.
I'm using a routed bridge and apart from the splat below i have got some
interesting other messages that aren't there in 4.3 (and perhaps are of
interest for the crash as well):
[ 207.033768] vif vif-1-0 vif1.0: set_features() failed (-1); wanted
0x0000000400004803, left 0x0000000400114813
[ 207.033780] vif vif-1-0 vif1.0: set_features() failed (-1); wanted
0x0000000400004803, left 0x0000000400114813
[ 207.245435] xen_bridge: error setting offload STP state on port

[ 207.245442] vif vif-1-0 vif1.0: failed to set HW ageing time
[ 207.245443] xen_bridge: error setting offload STP state on port

0x0000000400004803, left 0x0000000400114813
The commit message for the commit that introduced the "set HW ageing
time" error message, doesn't seem to tell
me much about it's purpose. If it's not related i can reported as a
seperate issue.
