The last message means the driver won't be able to work at optimal
speed, using DMA. Fixing this could be relatively simple, if you
provide the output of PCITools.Scan.

This is normal. When shutting down cleanly (e.g. using Ctrl-Alt-Del),
the current map of in-use disk blocks is written to disk. At the next
startup it will be read again, and disk garbage collection can be
skipped, to speed up booting. This message means the on-disk index was
not up-to-date, so a GC has to be done.

This is the GC being done...
