Comment 0 for bug 1856387

After the update to install kernel 4.15.0-72-generic (a bit over a week ago) my computer will not boot. On boot, all I see is the purple screen with:
Loading Linux 4.15.0-72-generic ...
Loading initial ramdisk ...
and nothing happens. Just sits there. I've waited about 5-10 minutes on occasion but to no avail.
I've checked a number of logs in /var/log but not found anything.

If I go into the advanced options and select kernel 4.15.0-70-generic, the computer boots normally.
