Is the problem still present in 2.6.37? Installed v2.6.37-natty from mainline PPA - the issue is gone. There are no warnings on the console after resume from standby and the bluetooth mouse works fine. Thx! Cool, thanks! |
Created attachment 27244 [details] Error message during resume If I suspend my laptop while the bluetooth mouse is connected, I get the attached error ("sysfs: cannot create duplicate filename") during resume and bluetooth is disabled. Tested on ubuntu maverick kernels (2.6.35-*) and mainline rc6, same results. It worked fine on 2.6.34 and 32. this is what I see when the mouse is not connected: ls -l /sys/class/bluetooth/ lrwxrwxrwx 1 root root 0 2010-07-25 10:31 hci0 -> ../../devices/pci0000:00/0000:00:1d.3/usb5/5-2/5-2.1/5-2.1:1.0/bluetooth/hci0 after connecting: ls -l /sys/class/bluetooth/ lrwxrwxrwx 1 root root 0 2010-07-25 10:37 hci0 -> ../../devices/pci0000:00/0000:00:1d.3/usb5/5-2/5-2.1/5-2.1:1.0/bluetooth/hci0 lrwxrwxrwx 1 root root 0 2010-07-25 10:39 hci0:11 -> ../../devices/pci0000:00/0000:00:1d.3/usb5/5-2/5-2.1/5-2.1:1.0/bluetooth/hci0/hci0:11 On resume from standby, the hci0:11 entry is gone on 2.6.32 and 34 kernels but remains there using 2.6.35 (seems like that's causing the error?)
