Since logging this bug entry, I suffered a corrupted root filesystem. I don't know for sure that the hanging on boot followed by me forcing reboots was the cause, but I guess it won't have helped. :/ I guess my SysRq S+U+S+B didn't work quite as well as I'd thought.
I was unable to recover the filesystem so I've had to reinstall Ubuntu 20.04. Luckily it was just the root filesystem that was lost so a reinstall was quite straight forward. I don't expect that a reinstall will have fixed the hangs (my kernel version is precisely the same as before), so I'll update when I see them again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877889 Title: Intermittent hangs on boot Ubuntu 20.04 on Lenovo E595 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1877889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
