bwfm driver failing on M2 Macbook Air

Hi,

I am running 7.9-current (same behavior on 7.8 though) on a Macbook Air
M2 using the bwfm wifi driver.  From time to time (more often than I'd
like), the driver seems to just stop working. After a resume but
sometimes also in the middle of working on stuff. Running ifconfig then
hangs for a long time and can't read half the info on the bwfm0 device.

dmesg only shows this when it happens:

> Jun  6 00:14:18 openbsd /bsd: bwfm0: missed beacon threshold set to 30 beacons, beacon interval is 100 TU
> Jun  6 00:14:18 openbsd /bsd: bwfm0: received msg 1/4 of the 4-way handshake from 7a:22:54:91:03:7e

Furthermore, on one specific WLAN that I join sometimes at a different
location, the WLAN somehow causes the system to entirely freeze, but the
kernel isn't crashing, so all I can do is a hard reboot. If the reboot
doesn't fsck the "old" hostname.bwfm0 file and continues with that WLAN
added to it, the kernel crashes on boot. I tried to get a dump but was
unsuccessful in doing so.

If there is anything I need to set to get a successful dump or anything
I can do in the debugger that opens on the boot crash, I can try to get
more info on it.
