I bought a Dell 17-5755 ten days ago and have been slowly configuring it. Came with Win 8.1, which I first upgraded to Win 10. Then shrank the primary partition to make room for Ubu and installed 16.04. Both have been running fine for the last week.
Yesterday, I started shifting over to the new machine in earnest, setting up Thunderbird and migrating from Evolution. While I was doing this, a notification popped up for a software update, so I started the software updater in the background and ignored it. I thought I had auto update off and don't remember pressing install, but next I looked it had updated and was asking to restart, so I've no idea what the updates were. I was in the middle of something, so pressed restart later. Later came and I restarted from the shutdown menu. The grub menu came up as usual, but I can't boot to Ubuntu and get the following:
/dev/sda6: recovery journal /dev/sda6: clean, 229524/107610112 files, 10311615/430426112 blocks [ 10.174300] tpm_crb MSFT0101:00: can't request region for resource [mem 0x9d899000-0x9d899fff]
Then it hangs, but something is going on as the fan starts winding up 10-15 seconds later. At this point all I can do it hard power off.
Win 10 still boots fine. The Ubu kernel is still 4.4.0-22, the same as before the updates. I guess I'm looking at starting over with a reinstall of 16.04, but any advice before I do that is much appreciated.
