I haven't tried the new patch but I can tell how iwm0 worked for me for
the past two years or so.

- list scan works without problems (I don't use it very often, though)
- wpa_supplicant connects instantly to my home network but it can take
  minutes to connect to iPhone hotspot
- 'firmware error' or similar messages can appear when my laptop is
  booting with a pretty low probability (< 1-2%)
- probability of hitting those errors increases significantly if
  I keep the laptop up for more than a day
- weak signal increases the probability

It crashed once (see kern/52583: kernel crash after iwm firmware error)
recently, I don't remember any other crashes.

My hw/fw are:

iwm0: hw rev 0x210, fw ver 22.361476.0
