Sounds like it's related to graphics-related data, possibly swapped out to disk -- say the contents of a frame-buffer was swapped out of the graphics card into main memory..and from there, swapped out to disk swap space.
POSSIBLY what is initiating this is the graphics card trying to access the swapped-out data in main memory, not finding it, and initiating main-memory page swaps ... but unfortunately, the kernel

eventually, after 30-45 seconds, all of the memory shuffling and memory page-swapping is finally done, and your system freeze ends.
I don't think that is the case, because it doesn't explain this:

The disk port is not responding, so the kernel decides to resets it. During that time, nothing can be read from the disk, and all processes needing i/o are stopped, frozen.
