Public bug reported: On my Thinkpad SL510 I get a loud beep when opening the lid to resume from suspend. Resuming seems to work as expected, no obvious other symptoms occur. The beep when closing the lid sounds normal: Quiet and about 130ms in duration. The duration of the loud beep is about 50ms or sometimes even shorter.
The same symptom has been mentioned on this closed bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1447331/comments/14 I first experienced this after upgrading a freshly installed 14.04.1 to 14.04.2 via the LTS Enablement stack to Kernel 3.16. https://wiki.ubuntu.com/Kernel/LTSEnablementStack Yesterday a fresh install of 15.10 Beta 2 on the same hardware showed the same symptom. Resuming from suspend seems to work in both cases. The loud beep was not present in 14.04.1 with Kernel 3.13. lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04 Not sure why it gives 14.04.3 above, since I never upgraded to that. It might also be worth mentioning that since installing the LTS Enablement stack I keep getting updates for Kernel 3.13 and also for 3.16, from which I can choose at system startup in GRUB.
