..drop the "quiet" part until you have fixed this issue,
you also might try "verbose" and "debug" for even more
error and warning messages.

..can also be done on a per boot basis; on boot-up, simply
hit "e" to edit "quiet" out of the boot command line,
then just boot to see them thar non-quiet messages.

Scenarios always come in sets of three:
best case, worst case, and just in case.
