This has been a problem ever since I got this laptop, but recently I
managed to fix it by downgrading the ibt firmware. I downgraded the
/lib/firmware/intel/ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq file to this
version
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/intel/ibt-
hw-37.7.10-fw-1.80.1.2d.d.bseq?id=fb328183532ffc7a1a54e84fb53467e275a95b79
and after that all problems stopped.
