_______________________________________________________
Details:
Grub release: 2.02~beta2-9ubuntu1.12+7.0trisquel5 (but the pre-build rom
image could be different)
Libreboot release: 20160907 (coreboot 377rc98)
May be related to bug #47374.
Test procedure:
- power off
- power on
- mash down key until menu timeout cancels
- c for command line
- ls
If the DVD drive is full, this spins it up twice, then returns a list of
devices, including partitions on the DVD.
If the DVD drive is empty, this hangs, apparently indefinitely.
Hold the power button, for a disgraceful shutdown, to recover the machine.
I wonder if the syntax for discovering the existence of a DVD drive should be
different from the syntax for discovering the set of partitions on the disk,
because they take very different amounts of time.
Regards,
James.
