Does my one-liner fix that case too? Now that I've been able to scan most of my mail; it looks like the one-liner should just go in. Restricting module loading from async work to only non-blocking is not a big deal, and it seems that userspace in various distros is really broken (and breaks on scsi already today), but that is not something we can really fix quickly. The sad part is that the userland is unlikely get fixed unless it shows breakage, and we can't break it (obviously). I don't know of any good other solutions; right now it's mostly the partition scan (which is already mostly async on scsi since a really long time, just in practice fast enough unless you have a big server). (The __init thing in modules is separate and easy to fix, but without the other stuff being fixed there's no point)
