[Bug 1091385] Re: BUG: unable to handle kernel paging request at ffffffffa0754318

 

Eduard Biceri-Matei, as per http://us.acer.com/ac/en/US/content/drivers
an update is available for your BIOS (V1.30). 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

Thank you for your understanding.

** Description changed:

  While trying to upgrade kernel to 3.5.0-21 via update manager
