Public bug reported: I was using kernel 4.19.20 with ubuntu 18.10 and it was working fine. Upgraded to 19.04 and it now boots approximately one attempt every 5. Doesn't depend on the kernel I choose (I have both 4.19.20 and 5.0.0 installed).
If I use the default Ubuntu boot entry, I get a black screen (when normally it would prompt for the disk decryption password). If I go to advanced options and choose a kernel (doesn't matter which one or whether it's recovery mode or not) then I get "Loading linux <version> ..." "Loading initial ramdisk ..." then nothing. Ctrl-alt-del doesn't work, power key needs holding for 10s to turn off. I've followed the steps to get it to print more output (gfxmode text, remove quiet, splash, vt options) but it doesn't give any more debug. I don't know if the problem is in grub or in the kernel. It's really odd that it works sometimes - I haven't spotted a pattern to that yet. I've attached a video of the boot process (I'd added an extra line to the grub script to make it print "Booting..." after loading the initial ramdisk, but that doesn't make a difference to whether it works or not). Sorry about the focus - phone cameras don't like big blank spaces. Happy to try more debug options, but have limited time so might not be quick to respond. Asus Zenbook 14, in case that makes a difference.
