It wasn’t. The actual root cause sat one layer below the kernel entirely — and getting from “random freezes” to “confirmed fixed” meant cross-compiling ZFS off-machine because the live system couldn’t survive its own build, then reverse-engineering an undocumented Ubuntu encryption mechanism that no upstream package ships. Here’s the full chain, and what’s worth keeping from it.
