Public bug reported:
Hi,
after plugging in an USB device, it doesn't get noticed until I say lsusb in
terminal - then it activates properly.
Maybe it is related to what I get in dmesg (complete output attached):

[ 28.404369] Disabling IRQ #18
I tried booting with the irqpoll option, the oops didn't show up in
dmesg and hotplugging worked, but integrated trackpoint motion was very
sloppy (as if processed only 10x/second or so). This bug was already
present in 2.6.22.
