Hi,

I also get kernel panics on every distribution I tried (and I tried nearly all), I tried two different SD cards (only have two).
I could get to run an Android build though. I checked for solder bridges but I coudn't find any. Anything else I can try? (I have the 4gb model)

Try different SD card, it is likely that your SD is just broken.

getting the same error. Rock64 4gig version. Multiple memory cards, multiple build OSes

getting the same error. Rock64 4gig version. Multiple memory cards, multiple build OSes

Please check whether stock Android build also has the memory crash issue. If still getting Kernel Panic, please file a support ticket at support.pine64.org

I saw a kernel panic w/ xenial-minimal-rock64-0.4.17-85-arm64.img after I unplugged a USB 3.0 hard disk (nothing was mounted on it).  Seems like the OS thought it was still connected.

Playing with jessie-minimal-rock64-0.5.7-101-arm64.img now, and don't see the same issue.  It does take several seconds for it to decide the USB device is no longer available when I unplugged the cable.  Nothing was active when the cable was unplugged, it just spewed the following to the console :

Edit: Looks like the latest jessie minimal also panics after disconnecting USB 3.0 device. Filed a issue on github, with ayufan (not sure if it was the right project page though).
