After the reboot back to 3.13.0-49 system works fine, although filesystems were dirty. Didn't try it the second time - this system is too important for experiments.

lvm, as per http://www.asrock.com/mb/AMD/990FX%20Extreme4/?cat=Download=BIOS an update to your computer's buggy and outdated BIOS is available (2.70). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-2.70 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.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/1460284 Title: BUG: soft lockup - CPU#1 stuck for 22s!

[kworker/u16:5:142] Status in linux-lts-trusty package in Ubuntu: New Bug description: Kernel has been upgraded from 3.13.0-49 to 3.13.0-53, several minutes after the first reboot with the new kernel I noticed high wio while syslog was filling with messages listed below. When I tried to reboot (shutdown -r) it posted reboot messages to all console windows and then locked up - no reaction to keyboard, no ping response, had to powercycle it. After the reboot back to 3.13.0-49 system works fine, although filesystems were dirty. Didn't try it the second time - this system is too important for experiments. It has been running on the same hardware for a couple of years with no prior issues. May 30 10:55:06 server kernel: [ 1702.612692] BUG: soft lockup - CPU#1 stuck for 22s!
