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?

Best regards,
								Pavel

v4.7 is okay.

v4.8 with

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

Seems to work ok.

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

I believe I tried just reverting
9c99e5e51988798af2a687ef9b1716dd79388550 before, but that did not
help.

I guess I'll try with these reverted, next:

pavel at amd:/data/l/linux-n900$ git show
9c99e5e51988798af2a687ef9b1716dd79388550 | git apply -R
pavel at amd:/data/l/linux-n900$ git show

pavel at amd:/data/l/linux-n900$ git show
62aa292b3eae920a80c2fd0ed0601a70328627f6 | git apply -R
pavel at amd:/data/l/linux-n900$

...seems to be broken already. I guess its time to
bisect... hmm. Tried bisecting, but soundcard does not work
there. Will do it manually...

Best regards,

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.

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,
