roelof van der kleij, as per http://www.dell.com/support/drivers/us/en/19/Product/optiplex-380 an update is available for your BIOS (A07). 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 just 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. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags removed: kernel-bug-exists-upstream kernel-bug-exists-upstream-v3.6-quantal kernel-bug-exists-upstream-v3.7-rc2-raring ** Tags added: bios-outdated-a07 kernel-bug-exists-upstream-v3.7-rc2 regression-potential ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064489 Title: BUG: unable to handle kernel NULL pointer dereference at (null); RIP: 0010:[<0000000000000000>] [< (null)>] (null) To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/1064489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
