Description of problem:
I installed Centos 7 on my laptop. The install went fine and I get to the login screen. I select the user and enter the password and then get these error messages.

[Firmware Bug] the BIOS has corrupted the hw-PMU resources (MSR 38d is b0)
mce: Unable to init device /dev/mcelog (RC: -5)
tmpfs: Bad mount huge
SR 2:0:0:0 [sr0] out of memory
Please enter passphase for disk vggroup00-var

If I enter the passphase it continues for awhile and prints some stuff and then reboots.

It has the latest firmware update and 12GB of memory.
It ran Centos 6 for years and also runs Windows 10 fine.


Version-Release number of selected component (if applicable):


How reproducible:
I have only tried this once.

Actual results:
Bad install, had to reinstall Centos 6


Expected results:
A workable install

When reinstalling Centos 6 I got a message that a 5GB partition didn't have a filesystem.  This could only be /var/log or /var/log/audit.  Note that the error message: "Please enter the passphase for vggroup00-var" in Centos 7.7.  When installing Centos 7.7 I used allocate space as a standard partition instead of LVM.  This is because I didn't have any spare LVM space and when you select swap it sets the space to 0.  (Also swap was allocated as a standard partition already). You then have to delete swap and add it again. I suspect that it allocated space in LVM even though I said allocate as standard partition and wiped out the LVM volumes formatting swap.  Any way, this is what I think the problem is!
