Summary0013983: No login possible because no keyboard/mouse for passphrase before mounting encrypted partition
DescriptionSystem with Centos-7 and kernel 3.10.0-514.26.2.el7.x86_64 works well.
All partitions of Laptop are encrypted.
At boot, I am asked for pass phrase which successfully unlocks partiotions and boots further.

After upgrading to kernel-3.10.0-693.2.2.el7.x86_64, there is no keyboard available to provide the pass phrase...
Not via USB, even if connected thereafter, not the built-in.
Also no mouse (USB) nor built-in track-pad on the X-screen.
Steps To ReproduceUpgrade Kernel to 3.10.0-693.2.2.el7.x86_64.
Reboot.
Get stuck with unlock encryption screen, since no key input possible.
Additional InformationAfter hard reset, rebooting in older 3.10.0-514.26.2.el7.x86_64 kernel, system behaves normally and allows entering the pass phrase, again.

There are no logs, since no disks/partitions to store them...
TagsNo tags attached.
