OK, i believe the wifi hard hangs are fixed.  i found the problem and have commited workarounds.  the latest builds on armbsd.org for -current include these fixes.  (now it doesn't hard-hang, i will look at porting the driver parts to netbsd-9.)

the wifi can still fail, but the system remains responsive and available and often can recover by itself, or with "ifconfig bwfm0 down up".  sometimes neither works and reboot is required.

Great job, it's working great as daily driver!

well, with all this positivity, I thought I should give another try
Maybe it's me, neither worked (9, current) armbsd.org/arm
9 just didn't boot, black screen, green light
current, I'm still cursing, always black screen, green light for 10s, out, capslk and numlk flash 1s
Then needs extra long press to revive pbp (20+s press pwr button)
(pbp appears dead, only led is red chg led, no green led, nothing happens)
Tried twice, wasn't sure of caps, num flash
Damn glad I know about extra long press
(emmc mrfixit, updated mrfixit uboot))

that's not good!  do you have uart?  i can't think
of any way to figure this out without that..

i would probably test with emmc disabled and use
just an sdcard.

I think this is u-boot related and it has nothing to do with NetBSD. If you're flashing NetBSD on sdcard, I would try flashing on eMMC a more recent u-boot such us this one https://github.com/pcm720/u-boot-build-s...v2020.07-1

Or disabling eMMC as mrgtwentythree already suggested.

My pbp is a virgin, back has not ever been removed.
So, no serial to uboot (why is there not a hole w/ rubber plug?)
I don't know how well pcm's uboot does sleep, no one has commented
Now, another distro has good sleep (elementry), 2 by now
Good sleep means few charging hassles, running from SD is feasible
As well, decent uptimes are possible, for those that care

Maybe 9 has a long fs expansion and takes 5-10m 1st boot?
I only left it 3-4m
current,, the reboot to recovery is just plain wrong
The 2 different uboots should be compared

Still experiencing wifi hard hangs in current using the bwfm driver (latest tested with the 2020.8.6 image from armbsd.org) - only happens when running firefox (79, 78, 77, 76 and 52). Usually happens within 20 seconds ~ 1 minute when streaming video or around 3~5 minutes with regular browsing. Keyboard gets completely unresponsive forcing me to do a physical reboot. However, has never experienced a wifi crash in TTY when I'm downloading large files like pkgsrc for example. Downloading large files in X also seems fine.

I also tried using a usb ethernet adapter - works a lot better but sometimes still hangs (~ 3 times / hour), doesn't hard hang though so just re-plugging it makes the wifi go back up. (adapter doesn't hang on the stock Manjaro image)

So, i though I'd give another try, with partial success
9 boots, I'm not sure why there would be rpi dtb's in root of boot partition,
when I moved them away and put the pbp dtb there, just booted
I did download a pbp image
current, still the same, almost looks like it is trying an EFI boot, there is an ESP
and *efi files. Same odd led flashes, ends up needing extra long press

Great work so far on the NetBSD image. I wrote a HEAD image from armbsd.org to the emmc (ld0c) and everything is far more polished than I'd expected.

I did get a bunch of bwfm0 checksum errors on my first boot with wireless. I've been leaning on the wireless since and haven't seen it again.

It's a pleasant bit of nostalgia to fire up xeyes again.

i've seen this keyboard hang.  i've very recently started trying to figure it out and hopefully will have an idea soon.  it's very annoying as it seems to affect all keyboard input as well as network IO, and i've not gotten any particular clues yet.
