Title:
If DVD drive is present system very often fails to start-up
Status in linux package in Ubuntu:
Incomplete
Bug description:
Whenever I power down, upon next boot the system just hangs with
Ubuntu at the bottom of the screen and the circle above going around
and around forever.
It happens nearly every ime I power down, but not every single time.
Rebooting rather that powering down works quite often.
At first when thing hung I would just hard power off by holding down
the power key. Then I'd use the live usb I installed with to run
Disks app. More often than not the vfat W95 FAT32 partition at sda1
was damaged. The first repair would fail. The second repair would
succeed. And then I'd be able to boot into my system again.
After chatting about it a little with EriC^^ in #ubuntu on IRC I
learned how to do Alt+Fn+PrtSc S, U, B or S, U, O. Sometimes just
doing either of those on the hang screen would result in it booting up
fine next time. Sometimes not.
After installing 20.04 (a fresh install on a brand new Samsung 860 EVO
1TB sdd hard drive) I copied back all the files in my home direct that
I'd backed from 18.04, including hidden files. This confused Firefox
so I had to delete related folders and then unintall and reinstall to
stop Firefox being confused. This might have nothing whatsoever to do
with this issue, just mentioning it just in case something else is
similarly confused. EriC^^ suggested I try adding another user and
seeing if the issue went away. On the first test (and some but not
all subsequent tests) it did seem that TestUser could power down and
reboot fine. But actually it didn't seem that different.
I powered down, rebooted, used live usb to repair Disk over and over
again for hours trying to find a pattern as to when it happened and
when it didn't, but failed to find any fixed pattern.
Eventually at one point it was taking a while to power down (or
reboot, I forget) and so I hit Esc and spotted that it had failed to
unmount /cdrom ...
... so then I thought I'd try completely removing my DVD/CDRW drive
and that made the issue go away.
Before filing this I put the DVD drive back in (but haven't since
rebooted), so not sure if apport has picked up it's details or not?
Perhaps I'll need to re-file the bug after booting with it present?
