After installation, it rebooted with no problems. I installed all updates, and on rebooting it failed to boot. The screen had unreadable graphics in the top third of it. On rebooting again, it booted okay, saying it recovered the journal. Sometimes, it takes 3 tries to get it to boot. Often, it gets most of the way into the boot process, then suddenly goes into the GRUB menu. I installed this system because my primary partition on the same machine started failing to boot much of the time. This failure started happening after applying updates. I was thinking something in the system files might be corrupted. But the newly-installed system has the same symptoms. After applying updates, I expected the system to boot successfully every time. Instead, it always crashes during the boot, or hangs, on the first try to boot. On the 2nd or 3rd try, it will boot.
