CPU architecture is x86, commit it happened on last time is 347733b.
Other possibly relevant factors:
* spinning rust storage
* 1GB RAM
* encrypted BTRFS root
* 4GB (encrypted) swap
* 128MB zswap
The last was not there when I originally submitted the bug.
The swap is relevant because if it's a timing issue it's very possible
some part of the code assumes reads are almost instant, which is not
true with swap, and delaying a read might be exposing a race condition.
