This change was made by a bot.

Same as others... Please test kernel parameter "pci=nocrs".

[André Santoro (asbnunes)]

I tried adding it and rebooting the laptop, still hasn't worked.

Maybe I did something incorrectly, the grub is looking like this right now
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nocrs"

[Hui Wang (hui.wang)]

Please test this kernel and upload the dmesg ($dmesg > dmesg.txt): https://people.canonical.com/~hwang4/lp1921649/

thx.
