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!
