Public bug reported:
Ubuntu 18.04.3, kernel 5.0.0-25-generic
When grub menu disappears, the screen remains blank.
I include a syslog file from a failed boot. The important part is at line 1175:
irq 7: nobody cared (try booting with the "irqpoll" option)
This laptop boots correctly with the 4.18 kernel.
