tshark -i eth0, eth1, lo are all empty. Works under 2.6.23.0 just fine. A quick scan of the log between 2.6.24-rc3 and current tip (-rc5) doesn't show any obvious fixes, but then again, what do I know. I'll check current tip on the weekend when I'll have the luxury to have my main system down long

Hey all, more data on my bcm43xx problem report from a few weeks back. By random chance I acquired a brain, and decided to rebuild my latest kernel pull with as many debugging options on as I could stand. Got the below, plus a dead keyboard (except for Magic SysRq) (but only if I let userspace com
