Subject: oops on wake up using usb-keyb/mouse on powerbook
Date: Thu, 10 Jun 2004 08:06:20 +0200
Hi!
I get this oops when I use a usb keyboard to wakeup the powerbook.
Kernel is 2.6.7-rc2, usb keyboard is infect a ps2 keyboard attached via
a usb->ps2 adapter.
Any ideas ?
Soeren.
The most interesting parts precede this message. Why did
the HC die? Stop that, and the rest should be fine.
kernel: ohci_hcd 0001:01:18.0: HC died; cleaning up
kernel: drivers/usb/input/hid-core.c: can't resubmit intr, 0001:01:18.0-1/input1,
status -108
kernel: usb 1-1: USB disconnect, address 3
kernel: Badness in hcd_endpoint_disable at drivers/usb/core/hcd.c:1359
That's just a WARN_ON(strange):
WARN_ON (!HCD_IS_RUNNING (hcd->state) && hcd->state != USB_STATE_HALT);
If the HC died, then it sure ought to be flagged as in HALT state.
