[B.A.T.M.A.N.] bat_events: page allocation failure (batman-adv maint)

Hey guys,

I've been installing a 9 node setup here in our cellar. They are all running B.A.T.M.A.N. adv 0.2.1-beta r1545 (so the current batman-adv maintance version in OpenWRT).

The result over night: - 1x: bat_events: page allocation failure - 3x: WARNING: at net/sched/sch_generic.c:226 0x801c3554() (those 3 had TQ values of about 10-15 in batctl)

For the last error, I'm not sure if this is related to batman-adv or to the madwifi driver. I was using OpenWRT trunk 18405 on all routers.

I'm attaching some backtraces. Sorry again I can't get more out of them than that with ksymoops. The first two ones are the bat_events problem, the others the scheduling thingy.

Cheers, Linus
