Could it be that the old laptop has a really new hybrid disk (the ones that have some flash and lots of spinning rust), and the disk controller chip in the laptop doesn't know how to deal with that. If you have a crappy cheap RAID controller with bad firmware, I could see it happening, but on a single disk without NVRAM cache, this is hard to imagine. Really hard to see how this could happen on an old laptop though. But then, on power down, the first IO gets silently abandoned by the disk. The file system then runs IOs that logically depend on those pending IOs, and those newer IOs make it to disk. At this point, there were no recent IOs, so maybe the problem will go away. Then do a clean shutdown with shutdown -h. Let it sit quietly for a minute or two, to make sure all dirty buffers have been flushed out to disk (and maybe within the disk to real persistent storage). Try the following: Completely quiesce the system (take down any Xwindows or user interface processes, take it down to a single login, and then kill all the daemons). You say this happens on every single boot. That shouldn't be an issue on a laptop since it has a battery.What is your disk controller. Still I get I've generally only seen that when the system dies because of a power failure. Heck, I even used the -f option to check it anyway. Every time I reboot, during boot I get the message Every time the filesystem is marked as clean. So far I like what I see but I have a problem that makes me concerned about UFS stability.
