Comment 68 for bug 522998

I seem to have the same issue with 12.10, kernel 3.5.0-19-generic. this is what I get in dmesg when trying to suspend:

[ 40.213352] xhci_hcd 0000:02:00.0: WARN: xHC CMD_RUN timeout
[ 40.213370] suspend_common(): xhci_pci_suspend+0x0/0x40 returns -110
[ 40.213373] pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110
[ 40.213376] dpm_run_callback(): pci_pm_suspend+0x0/0x140 returns -110
[ 40.213379] PM: Device 0000:02:00.0 failed to suspend async: error -110

interestingly, xhci_hcd seems to be not compiled as a module for this kernel? at least, lsmod doesn't show it, "lsmod | grep xhci" returns nothing.

I wonder how one can disable a module if it's compiled into the kernel....
