I was trying to improve GSM call quality, and hit problems in
v4.8-rc. Sound only worked for a while, then I tried to kill
cmtspeech_ofono_test, and could not, not even with -9 and could not
even reboot.

I went back to v4.1 (ok, quite far, I see), and problems are gone.

Does it work for you? Any ideas what to try... besides bisect?

v4.7 is okay.

v4.8 with

git diff ..mini-v4.7 drivers/hsi/ | git apply

Seems to work ok.

Hmm. I guess I made some error with the testing, because reverting
just drivers/hsi to v4.7 state results in non-compiling kernel

hsi changes from 4.7 to 4.8 are basically runtime PM enablement.
Does 4.8 work for you with just 9c99e5e51988 reverted?

No, according to the notes. But see above... and let me retry with
drivers/hsi _and_ include/linux/hsi reverted. No GSM audio and same
problem with shutdown. Oops. Sorry about the confusion.

Does it work for you? Any ideas what could be wrong?

Best regards,
