Thanks. I tested the proposed kernel and it does not prevent the crash, which still occurs under the same circumstances when cryptsetup open runs. It's possible, however, that the patch decreases the likehood of a crash. In a very un-scientific test the latest patched kernel crashed in 3 out of 10 attempts, while the stock unpatched kernel crashed in 6 out of 10 attempts.
To mitigate the issue, with both the original and patched kernels, I'm manually loading the dm-crypt module before running cryptsetup luksFormat. Note that manually loading the module between cryptsetup luksFormat and cryptsetup open does not prevent the crash. -- 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
