The suspicion was around either dm-crypt and TPM. At least one user has reported that these reverts have fixed the boot issue. These patches were applied recently, so the regression potential would be the previous status quo regarding TPM support. TPM failures have been seen before, but they seemed to be more about log failures, but no boot issues.
