urgent! linux 2.6.16 network bridge crash

[auther_bin]

Hello friends, I have config my linux box works as a network bridge. and
up/down switch is both cisco 35xx works with vlan. but when i connect it
into the network the box crashed right now. Puzzled!

btw, in the down(intranet) switch we connect 8 wireless AP.

tcpdump gives many many broadcast package like:

time serial M SRC_MAC > 1:0:0:0:0:0 sap aa ui/C

what's it?
flood? or the AP package or the cisco vlan? but whatever it is, the box
should not be crashed by it, right?

if the box do not use bridge, it will not crash at all.

Hi friend,

There is not much information (crash is more crash or more lockup?), so you
can only guess. Looks like a multicast problem (vs. vlan or bridge). Maybe
because of wrong MAC like here:

Otherwise you should try to enable and send more debbugging.
