This error message means hdparm got EINVAL back from an ioctl to get information. This is almost always a driver issue. I'd say 2 things to this: First, if a userspace process can cause a bus reset by calling a well-defined ioctl, this is a kernel bug. Second, hdparm doesn't run by itself, so it didn't create all those lines in your logs. I'm happy to leave this bug open while you take a look on your system for other things that may be calling hdparm (or calling the HDIO_DRIVE_CMD and HDIO_GET_IDENTITY ioctl()s directly), but I don't think this is likely to end up as an hdparm issue.
