  Stupid me. I didn't check card insertion/removal after boot.

Card REMOVAL when boot was WITH CARD:
  Instant panic:

rtsx0: Interrupt card inserted/removed
rtsx0: Card absent

KDB: enter: panic

Both panics are "debuggable", as keyboard is working in ddb and crash dump could be created. And I'm not sure, that GIANT in 2021 is good thing.
