PS: I'm also getting the following kind of messages from a wlan
interface that's on the bridge:

[ 268.976317] ieee80211 phy0: failed to reallocate TX buffer
[ 716.880515] ieee80211 phy0: failed to reallocate TX buffer
[ 1160.877677] ieee80211 phy0: failed to reallocate TX buffer

Could they be related?
