What!? A Therapeutic Reboot!?

[elfs]

This morning, my laptop had to undergo a therapeutic reboot.

On the bus, I noticed this morning that my laptop battery read 94%: 1:03, which to me was just wrong; at 94% battery I should have over two hours of performance left. Something was running away.

I pulled up the process monitor top and looked. The kernel USB hub server was the runaway, eating upto 95% of the CPU and basically eating the battery alive. This was apparently associated with my disconnecting the iPod and then suspending the laptop before the hub had a chance to register the disconnect.

A quick reboot and everything was well but, man, that's annoying. Reboot a Linux box? What is this, an abusive relationship?

I find that I can usually unload the usb module when that happens, solving the problem without a reboot. Only on 2.6 kernels, though -- the 2.4 kernels give me oopses when I try that.

I tried that. It just hung there on rmmod for about five minutes before I gave up waiting and issued shutdown -r. This is the first time it's happened in a few months of use, so I'm not too worried about it.
