Hi all. I'm using a vanilla linux-2.6.22 kernel. I just noticed I
get these messages while my laptop is sitting around doing nothing, 2
of my USB ports get disabled. I'm not sure what's causing them, to
reproduce I just let the laptop sit idle for maybe 5 minutes. rmmod
uhci_hcd and modprobeing it brings it back for a few more minutes but
the message pops back up. I'm using a Lenovo T61. Does anyone have
any possible suggestions or kernel patches I can try? Thanks!
