keyboard dead with 45b5035

[Pierre Ossman]

The patch "[RTNETLINK]: Send a single notification on device state changes." kills (at least) the keyboard here. Everything seems to work fine in single user mode, but when init starts spawning of logins, the keyboard goes bye-bye. Even the power button is ignored. :/

I've tried just creating another vt with "chvt 2", but that is insufficient to trigger the bug.

That solved it.

I wonder if that's also why modprobe tends to wedge up with the new USB announce thingy... Tomorrow's debugging will tell.

Perhaps not quite. When I returned to my laptop this morning, the keyboard was gone again. Did a hard reboot, and the machine locked up a few seconds after starting X. I'll see if it can be reproduced...
