Well, partially. Machine survived a dozed of detach-remove-insert-attach
cycles (which it definitly could not before).
However, it it still paniced on hot-remove-insert (could not dump):

Some other hot reinserts finished successfully.
Well, at least now it is significally better that before, if one does not
forget to detach ata channel before reinserting the device.
