Plus it looked very simple. That said, maybe Julia might have misspoken, and rc1 was ok, so I guess it's possible. The scan_mutex does show up in that "locks held" list, although I can't see why it would matter. But it does potentially change timing (so it could expose some existing race), if nothing else. But let's make sure Jens is aware of this too, in case it's some ATA issue. Not that any of those handful of 5.10 changes look remotely likely _either_. Jens, see https://lore.kernel.org/lkml/alpine.DEB.2.22.394.2012081813310.2680@hadrien/ if you don't already have the lkml thread locally.. There's not enough of the dmesg to even really guess what Julia's actual hardware is, apart from it being a Seagate SATA disk. Julia? What controllers and disks do you have show up when things work?
