The kernel failed to mount the initial root filesystem, which should have been put into RAM by the bootloader. It's strange that this is failing, and even stranger that the failure is intermittent. It would be really nice to get the full dmesg from the kernel, but that's difficult when the kernel panics that early in boot.
Now that we know the problem is intermittent, I think the next reasonable step is to establish if this really is a regression since 4.4.0-28. How often does this happen in 4.4.0-31? If it's reasonably frequent and you can do enough successful reboots into 4.4.0-28 to give confidence that the bug doesn't exist there, then we could bisect to try and figure out which change introduced the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605731 Title: Kernel 4.4.0-31 Causes kernel panic at startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1605731/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
