[Bug 1241726] Re: [RT3090] modprobe -r rt2800pci crash in kernel (kernel-bug-exists-upstream)
pranith, as per
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+7+Series+Chipset+Boards&ProductProduct=Intel%C2%AE+Desktop+Board
+DZ77GA-70K an update is available for your BIOS (0066). If you update
to this following https://help.ubuntu.com/community/BiosUpdate , 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.
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Thank you for your understanding.
