We're now opening the LUKS device using the master key directly and the crash is happening again in both the original 4.15.0-54-generic (buildd@lgw01-amd64-014) kernel or the patched 4.15.0-54-generic (arighi@kathleen) kernel. The backtrace is very similar but unlike the previous scenario it happens even if delays as large as 5000 ms are placed between partition table re-reading and commands.

The LUKS device is created and accessed using the following commands:

# cryptsetup -q luksFormat --type luks2 --pbkdf-memory 10000 --master-key-file <keyfile> <device>

# LD_PRELOAD=/lib/no-udev.so cryptsetup open --master-key-file <keyfile> <device> <name>
