Title:
Oops during snd_hda_in
Public bug reported:
Occuring on init. Laptop's LG M1 Dual Express.
Used to work some time ago in 2.6 or so. Works in Windows.
Strack trace:
Oct 10 14:09:39 bentley2 kernel: [28736.755733] snd_hda_intel :00:1b.0: PCI
INT A -> GSI 22 (level, low) -> IRQ 22

Same here. It can be reproduced easily.
Save the battery state, reboot, open up pref screen again, and here you
go, with battery state empty again. Looks like it doesn't save it, nor
it tells power indicator to appear in the status bar.
