Update:

After several more suspend & resume cycles I managed to get back
into the non-working state where every network call hangs.

I've upgraded to 3.2.0-rc5, which results in same behaviour.

Attached are latest dmesg outputs, with changing behaviour
(3.2.0-rc4-00255-g77a7300.dmesg.xz) and the usual does not
work on bootup status (3.2.0-rc5.dmesg.xz).

Cheers,

Nico
