Occasionally my Pi3 will crash during boot and hang on the error message:
Fixing recursive fault but reboot is needed
Manually power cycling it sometimes fixes this, but sometimes the error immediately re-occurs. What's causing this?
It seems to occur more often if I try to SSH into my Pi while it's booting.
I'm running Ubuntu 16.04.
Edit: I'm also occasionally seeing the error:
Unable to handle kernel null point at virtual address
during boot, which also hangs.
Would this be caused by a corrupt or defective SD card? I'm using an 8GB Kingston, which is reported to work.
