Quick note on a workaround: I've found on my pi400 that reverting to kernel 1007 works around the issue. If you've still got 1007 installed (a quick "ls /boot" should confirm that if you see lots of *-1007-raspi files lying around) you can temporarily switch to it like so:
$ sudo flash-kernel --force 5.8.0-1007-raspi This will force flash-kernel to copy the older kernel (and dtbs etc.) to the boot partition instead of the latest (obviously you need to reboot afterward to use the 1007 kernel). flash-kernel will warn in its output that installing another kernel will just overwrite this, but that's *probably* what you want anyway (assuming the next upgrade fixes this). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907432 Title: Raspberry Pi 400 Kernel Panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1907432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
