Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:

See Bugzilla for the full thread.
Anyway, I'm adding this regression to regzbot:
#regzbot introduced: e4f5073d53be6c https://bugzilla.kernel.org/show_bug.cgi?id=217996
#regzbot title: pm support for Intel 7560 makes the modem stops working after resume
Thanks.

Any quick fix for this issue? alternatively we will probably revert e4f5073d53.

FYI, the reporter had uploaded full dmesg output on Bugzilla.
Also, he noted shutdown abnormality:
> also I should mention, that if this error occurs, I am unable to shutdown my system anymore. "poweroff" does not turn the laptop off, it simply triggers a reboot, where the modem is still not functional. Only pressing the powerbutton >4 secs "resets" the device.
Thanks.

Chetan can't be contacted as sending to his address bounces (error 550)
(had he left Intel?). Last message on LKML is this culprit patch [1].
Hence, revert for now.
Thanks.
