Just a note: 1. The utopic version of hwclock has a 10 second timeout but does not report a timeout error (which is misleading) 2. The trusty version reports the timeout, but prints the errno from the previous system call, so the error message is misleading 3. When I get hwclock time-out the following kernel message appears:
hpet1: lost 20 rtc interrupts 4. I've tested this back to 3.12 and we see the same issue there too. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1333569 Title: Hibernate with fwts will cause hwclock command to time out Status in Firmware Test Suite: Incomplete Status in “linux” package in Ubuntu: Incomplete Bug description: This issue was found in bug 1327075 If you hibernate a system with fwts, and run the hwclock command, the hwclock command will complain that it was unable to access /dev/rtc, you have to reboot the system to have it back to normal. ubuntu@201401-14542:~$ sudo hwclock -r ; sleep 3;sudo fwts -P s4 --s4-device-check --s4-device-check-delay=45 --s4-sleep-delay=120; sleep 3 ;sudo hwclock -r Tue 24 Jun 2014 03:31:27 AM EDT -0.875913 seconds Running 1 tests, results appended to results.log Test: S4 hibernate/resume test.
