Description Thiemo Nagel 2010-04-12 19:34:13 UTC 
Hello!

Sometimes, my Eee PC 1000HG fails to suspend and I get:

[ 5028.677105] Suspending console(s) (use no_console_suspend to debug)
[ 5028.695012] option: option_instat_callback: error -2

[ 5029.928306] PM: Device 0000:00:1d.7 failed to suspend: error -22
[ 5029.928314] PM: Some devices failed to suspend

Running

  rmmod ehci_hcd && modprobe ehci_hcd

cures the problem.

The incidence is pretty low: 3 times in 3 month so far.

Let me know if you need further info.

Cheers!

Some additional information:

Up to now, I've observed this issue with 3 different kernel versions:
* 2.6.32-5 (Debian)
* 2.6.32.7 (vanilla)
* 2.6.32-11 (Debian)

The problem can be cured by a hibernate+resume cycle.

I assume that it's somehow related to the Huawei E620, because that's the USB device that was active during the suspend attempt.
Comment 3 Greg Kroah-Hartman 2012-02-22 21:49:46 UTC 
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing 
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
