No.  From all the comments I saw your are not taking the wlan interface
of iwlwifi down *before* suspending as mentioned in the bug in "See
also" on one of yours.

Anything which will come back from resume will not work or crash your
machine.

Try to implement taking the wlan interface down (destory) before suspend
and start it again after resume (create) and see if that helps.

In case poeple wonder -- internally our native drivers do not do much
ddifferent for net80211 but LinuxKPI needs its own driving.  It's on a
list but currently the "hang on boot" is more pressing as other things.
