I have had several of those on my laptop since I upgraded to
10.0_BETA (then 10.0 then 10.1 and it still crashes the same way
from time to time). My laptop is a Clevo and it also has an iwm0
Wi-Fi device.  When it ran NetBSD 9, I never had any problem with
iwm0.

With NetBSD 10, the iwm0 firmware frequently fails to load at
boot time although running dhcpcd manually afterwards generally
makes the firmware to load properly.  I never see throughput
above 2 MB/s with iwm0 on NetBSD, which is really slow, but, when
I boot the same system with Linux on an external disk, I have
never had any problem with Wi-Fi and I have much higher
throughput.

iwm0 seems quite buggy as it is...
