hi everyone,
just subscribed.
I'm using an ACER travelmate 4001WLMi and someone showed me that it has some problems with the ehci usb driver.
without debug, i get the following:
Dec 20 00:41:04 archon ehci_hcd 0000:00:1d.7: fatal error Dec 20 00:41:04 archon ehci_hcd 0000:00:1d.7: HC died; cleaning up
with debug, this is what shows:

It seems to me that the ehci driver gets started ok, but while hotplugging devices, it crashes and bails out.
Is this hardware related? Is this a known issue?
