I was able to reproduce the problem after a few tries with the 5.7.0-050700-generic kernel. I then started trying older kernels. It appears the problem started somewhere between 4.10.0 an 4.18.0. But sometimes it takes several tries to reproduce, so I'll continue some ad- hoc bisecting to see if I can narrow it down.
For posterity, here is how I'm reproducing. It may take several tries, but it seems to happen about 1/3 of the time. I don't expect you to need to follow all of this for now: Using CircuitPython 5.3.0 on Adafruit Metro M0 board. Connect to REPL and do: >>> import storage >>> storage.erase_filesystem() can cause an immediate kernel crash, or it might be delayed by several seconds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871143 Title: Kernel crash during USB device enumeration or mounting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
