Vladimír Kriška, as per http://support.lenovo.com/us/en/products /laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t450s an update to your computer's buggy and outdated BIOS is available (1.10). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 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, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-1.10 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.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/1438257 Title: BUG: unable to handle kernel paging request at 00007f555e269268 Status in linux package in Ubuntu: Confirmed Bug description: I started VirtualBox, and after some time whole system froze.
