Hi,

I am currently trying to use NanoPi R2S as my hone router. So far I have 
successfully booted OpenBSD with the instruction given in this 
(https://reddit.com/r/openbsd/comments/ggliod/facetime_audio_cause_openbsd_router_cease_to_work/fqf88rx?context=3)
 reddit comment. The device tree blob was provided by Patrick Wildt.

Everything works with no problem, however after being up ~24 hours the ure(4) 
interface would cease to work. No packets can arrive in and out from the ure(4) 
interface, although everything else still work. I can still ssh into the 
machine via the dwge(4) interface.

Upon further investigation, it seems that this has previously occurred before. 
The similar problem was caused by watchdog timeout error, however this was 
supposedly fix in around August. Interestingly, there is no mention of watchdog 
timeout in the dmesg, what I got instead was this:

ure0: usb error on tx: IN_PROGRESS
usb_insert_transfer: xfer=0xffffff8004b707c0 not free

I don't know how to reproduce this except to wait ~24 hours and wait for it to 
fail.

Anyone has any clues of what's going on?

Regards,
Wind
