ide0: unexpected interrupt, status=0xff, count=1


That part looks bad, indicating a hardware fault.
Most likely with where the IDE hard disk cable connects to the mainboard. The connector there (both parts) is extremely fragile, and frequently falls apart.

This means, the ribbon cable half can separate from its connector, which sometimes is curable by recrimping it.

But it more often means the "IDE header" (pins soldered to the mainboard) have broken their solder joints. Repairing those requires a practised and delicate touch with a temperature controlled soldering iron. Even just examining the connection requires good magnification to see the solder breaks.

Capture / post a better copy of the serial log and then we'll know for sure.
