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> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835279 Title: 4.15.0-54.58-generic 4.15.18: oops/BUG on LUKS open To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1835279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
