2.6.14-1.1739_FC5 fails to sleep on a Powerbook
Last modified: 2008-08-02 19:40:33 EDT
Closing the lid on my powerbook fails to sleep. I don't have the full log,
but the adb driver is apparently failing to respond to the sleep call. Is
this a known problem?
It's probably not ADB, ADB just happen to be the last to be woken back up after
the failure. It's generally a USB problem (as most PM issues are ...)
Yeah, I don't have the dmesg handy, but adb was the last thing I saw on the
screen. When I get home I'll try to get the complete output and post it here.
I'll also see if rmmoding the USB drivers before I close the lid helps.
Here's the relevant part of the logs after a suspend attempt. Looks like
hci_usb is the problem. If I rmmod it prior to closing the lid, sleep works
hci_usb 1-1:1.1: no suspend?
hci_usb 1-1:1.0: no suspend?
Could not suspend device 1-1: error -16
adb: starting probe task...
adb devices: : 2 c3 : 3 1 : 7 1f
ADB keyboard at 2, handler 1
ADB mouse at 3, handler set to 4 (trackpad)
adb: finished probe task...
Driver sleep failed
Sleep rejected by devices
The hci_usb driver lacks a suspend method. A workaround is to add 'hid2hci
--tohid; sleep 1' in the sleep) section and 'hid2hci' in the wakeup) section of

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
Recent FC6 kernels seem to suspend/resume just fine (though they're awfully
verbose when they do it but that's another issue altogether).
