v4.8-rc: GSM audio causes trouble

Hi!

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.

Best regards,
								Pavel
