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.
