I also tested pm-utils from Natty (1.4.1-5). As mentioned in the last comment, 49bluetooth is not actually executed because I was not testing on a Thinkpad.
I removed the thinkpad-related part, left only 13-49bluetooth- sync.patch, and added "/sys/module/btusb/refcnt". The value does not reach 0. However this should make the CPU waits a while before the time out. But the hang is still observed in my testing. (A gentle notice is that the goal is 250 successful S4 iterations.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/715643 Title: Bluetooth modules cause random S4 hangs -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
