This can be fixed by appending "xhci_hcd.quirks=270336" to the kernel
command line.

Whenever I attempt to poweroff my system, whether it's from the desktop
or the via "poweroff" on the console, my computer goes through the
proper shutdown procedure, seems to hang a little bit, and then simply

What distribution and version are you running? Are you running a Legion

My EDID doesn't seem to parse correctly... Which is probably at least
part of the problem. The fact that it works on the Nvidia driver
suggests that EDID parsing could be the problem (I'm sure Nvidia does

Public bug reported:
All 3 models need the appropriate HDA verbs sent to properly initialize
the sound hardware.
Additionally, the Legion 15IMHG05 needs automute disabled otherwise
speaker output will not return after removing headphones.
The good news is that I have working patches for all 3.
I applied the diff to 5.13.8... and it worked!
Thank you!!
