Hi,
I hit issues booting my laptop when running on battery thanks to commit
765e40b675a9566459ddcb8358ad16f3b8344bbe given that I don't have any ssd/nvme
on it. Given that I decided to disable the option to default scsi to
multiqueue, but still my booting issues persist. For a while I was reverting
this patch successfully but nowadays that is not anymore possible. Would it be
possible to accept some patch like the one attached to ease this situation?
Thanks!
José Pekkarinen.
