Public bug reported:
Regression after the Kernel Updates after april 26th, all result in Failed Boot
with LUKS on LVM.
Occurs on several IBM PC symtems with UBUNTU 16.04 and Xubuntu 18.04.
Fresh installation with the newest version and update does not give a better
result.
All Pentium ibm pc´s with Ubuntu 16.04 and one with Xubuntu 18.04 have been
installed with the standard full HDD encryption, LUKS on LVM. Decryption at
startup worked fine for years until april the 26th of 2019. Since these
(kernel) updates the regression problem occurs and stays.
After Powering on the system, the boot process will start. LUKS asks for the
key.
After entering the key the decryption will start, but comes to an abrupt end
before the startup (boot and decryption) is finished. Nothing is possible in
that situation. The screen is frozen. The HDD is inactive. Switching off the
power is the only way out.
After this failed boot, restarting the system, the grub menu shows for
some seconds. After that LUKS asks for the key. Entering the key results
in a completed startup and normal usable system.
Is this enough information to understand the problem ?
Or let me know what other information you need.
Is there a way out of this problem ? Or
Is there a simple way to circumvent this problem ?
Kind regards
