Somewhere post 2.6.24, the kernel started getting very temperamentful. I
experience random hangs and wedges very often.
Primarily, the udev startup locks up. If I abort it, it just locks up on more
or less every action after that. Some quick debugging showed that I had a whole
bunch of modprobe processes sitting around. The new
CONFIG_USB_ANNOUNCE_NEW_DEVICES setting makes every startup of udev lock up
consistently on at least two machines. It does not seem to be the root of the
problem as disabling the option just makes the bug very unlikely.
I've also seen a couple of lockups in X. Might be a different expression of the
same bug, but the effect here is a complete wedge of the user interface. It
seems the rest of the machine also locks up, but I haven't confirmed this.
Anyone else seeing these problems? Someone should as I've seen the problem on
both a Lenovo and a HP laptop here.
