control-alt-f2 I think will do it; depends on the install media
whether you get a prompt or some other process showing logs, so try f2
and if you don't have a prompt try f3, then f4, etc.

Yes. Insert USB then:
lsblk to find out what /dev/sdXY is
mount /dev/sdXY /mnt
cp dmesg /mnt/
umount /mnt
Now to post it to that bug report you have open...
