The changed "driver" has to be in the kernel, if it changed.
Sure but I mean that it will help narrow the problem to some subsystems.
Unfortunately we don't know what patches your distro kernel applied between
the two versions, but if you can figure that out from their changelogs, it
may help you narrow this down to just a few patches. These ones would
typically have "ata" in their subject line (sometimes "sata" or "libata"),
that could significantly limit the number of possible candidates. If you
can't find this there, you'll have two possibilities left:
- either retry with an official kernel from kernel.org
- or report a bug to your distro
