Re: Kernel crash on RPI 2 + 3, netbsd-current from May 28, earmv7hf



I don’t see this.. All I do is the thermometer icon once I have builds running with concurrency greater than 3…

Apologies for the bad screenshot. Indeed it is almost in best focus, but my little HDMI monitor screws it up, fighting with the resolution. Was not able yet to reconfigure for a lower one.

Sure I can transcribe into a PR. Was seeing the exact same crash multiple times, with both RPI2 and RPI3 devices, so my intuition tells me this is not a power supply issue. But nevertheless a good point. Might try with another one and see how this changes things. During boot, I see the kernel hanging from time to time, always in the USB detection area. Maybe another indication for bad power supply? Or have you faced this yourself?

Thx,
Ben
