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.

Best regards,

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

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

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,

Pavel

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 ad60db2f9fe3367e60a21fc0afe19999516f8b27 | git apply -R pavel at amd:/data/l/linux-n900$ git show 4e552310cdf0c81210b5fc9173f7cf497eeb9feb | git apply -R pavel at amd:/data/l/linux-n900$ git show 604fdfa45886f04ad6070c1b8266c7f4154bc497 | git apply -R pavel at amd:/data/l/linux-n900$ git show d2b8d695c61c4d2864eee900bebc2ced4f425645 | git apply -R pavel at amd:/data/l/linux-n900$ git show fa1572d956ee072e965da01d2c46f10d2b67d017 | git apply -R 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,
Pavel
