[Bug 1504484] Re: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
Yuan Li, thank you for reporting this and helping make Ubuntu better. As
per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-x-series-laptops/thinkpad-x250 an update to your
computer's buggy and outdated BIOS is available (1.17). 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, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.
Thank you for your understanding.
