I am not sure how freezes that could be fixed with key press could be 
related to panics around storage. I would try to go two different ways:
  - for panics, if dumping is not possible, I would try to resolve 
address of the "instruction pointer" from both messages with `addr2line 
-e /path/to/kernel address`.
  - for freezes I would try to look on eventtimers(4) subsystem: check 
what timer is used, try to switch to different one, try to switch into 
periodic mode.

Since cause of siis timeouts in SATA2 mode is also unclear, I can't also 
exclude that it may be somehow related.
