Goran Dzhambazov, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (3238). If you update to this, does it change anything?
If not, 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 Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Thank you for your understanding. ** Tags added: bios-outdated-3238 needs-oops-log needs-upstream-testing regression-update ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1212473 Title: System freezes after kernel upgrade Status in “linux” package in Ubuntu: Incomplete Bug description: I am running Ubuntu Precise 12.04 32-bit.
