[Bug 1442951] Re: kswapd0 takes 100% of cpu and system is unresponsive

 

zubu, thank you for reporting this and helping make Ubuntu better. As
per http://us.acer.com/ac/en/US/content/drivers an update to your
computer's buggy and outdated BIOS is available (2.19). 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.
