Adding "earlyprintk=efi,keep" to the command line only gives me 1 line:
'Memory KASLR using RDRAND RDTSC...'
If its quite low res, only this line, if i also get 'error: can't find
command `hwmatch` then its a bit more high-res.

Title:
Purple screen hangup during boot
Status in linux package in Ubuntu:
Confirmed
Bug description:
Specs:
Ubuntu 19.04 fresh install, everything updated
Firmware is latest (Bios version 300)
Asus vivobook s14
LVM disk encryption
Steps to reproduce:
- Install ubuntu 19.04/18.10
- Reboot
- Purple screen indefinitely
Setting kernel cmdline args only to ro nomodeset seems solves it.
After some debugging session with #ubuntu with different cmdline args,
it seems now the default one works too. I have not edited anything,
but now i am unable to reproduce it.
