Hi Nick!

I'm original bug reporter. We have probably same issues so having one bugreport
instead of two would be better but nevermind. I didn't respond on my bugreport
because I had nothing to add beside my logs which were probably missed by devs
basing on their answers to me.

For the record I attached my logs in original bugreport here:
https://bugs.freedesktop.org/attachment.cgi?id=131875

I can confirm this bug affects kernel 4.14 as well. I would be glad if devs can
give us any clues about this. I noticed that we both use KDE, maybe it's
related?


I wanted to clear some off-topic things:

1. The acpi errors are from hp_wmi kernel module. You can disable this module
by creating blacklist.conf file in /etc/modprobe.d and add line "blacklist
hp_wmi" to it. On my machine (similar to yours) disabling it doesn't have any
repercussions.

2. Are you sure you have still sound problem on 4.13 kernel? To my knowledge
those sound issues were fixed long time ago and you can safely drop
"acpi_backlight=vendor "acpi_osi=!Windows 2013" "acpi_osi=!Windows 2012" from
cmdline.
