For what it's worth, I didn't mean that the systemd people shouldn't triage the bug.
I meant that I suspect @poettering was mistaken when he said the current maintainers didn't collectively have "the expertise and understanding to maintain this properly."
As far as I can make out, there was nothing particularly hardware-specific about the bug. The bug was that udev was assuming that there could be no more than one disk per SATA host node, which turns out not to be the case.
`udevadm info` output would have been enough to see what was going on, which I'm sure the reporter would have happily supplied.
