>Description:
after the recent net80211 and iwi(4) updates, the card completely stops
working after APM suspend/resume.  this used to work sans the need to free
enough memory to allow loading firmware, which manifested itself with
messages:

 iwi0: could not allocate firmware DMA memory
 iwi0: could not load main firmware

but there is no indication of such an issue this time.

removing the firmware using iwictl -k doesn't help either, the card just stays
silent.

if i repeat "ifconfig iwi0 down up" quick enough, from time to time i get the
following message from the driver:

 iwi0: timeout waiting for master

>How-To-Repeat:
update to recent -current,
try to use iwi(4) after apm suspend/resume

>Fix:
n/a
