Comment # 24 on bug 1231599 from Rojon

Hello everyone,

I want to report that even with the patch by Takashi Iwai (thanks!), I am
regularly experiencing hard freezes which force me to hard reboot the system.
While this most often happens when resuming from sleep, I just had a hard
freeze  during normal usage (AFAIK). I have been updating my system daily ever
since.

1. rpm -q --changelog kernel-default | grep -C2 1231599

- Bluetooth: btmtk: Remove resetting mt7921 before downloading
  the fw (bsc#1231599).
- commit a3c998f

2. cat /etc/os-release

For the moment, I switched over to kernel-longterm to boot from there. If I can
provide additional information, I am happy to provide them.

Have a good day :)
