freebsd-arm Digest, Vol 744, Issue 1

[Furkan Salman]

Hello,


I have a Khadas Edge-V which is also RK3399, I have enabled the big core as explained by sergey and I have been running it with all 6 cores and compiled opnsense images for testing which took around 7+ hours and it didn't crash for me.


It never crashed in my regular use and I am just using it headless and not a DE, AFAIK if you have NVMe connected and you enable all 6cores then it crashes. 



If there is any test you want me to do then please do let me know.

Thank You.

Yes, anything USB related does seem to cause a panic still. Furthermore, 
even without any USB device plugged in and hw.ncpu left alone, I've noticed 
that the system will simply hard lock up after a relatively short period (2-24 
hours) of time on both a Rockpro64 and a RockPi4. Connecting via UART doesn't 
show anything interesting, it just simply stops working.
