This is not only a question of the firmware revision.
Many cards have an eeprom with the firmware on the board. The TDA10046
automatically tries to boot from this. The eeprom address is controlled
with a GPIO pin. IF this pin changes while the chip boots, it will crash
and possibly not recover. This entrie mechanism is hard to control.
The card specific configuration structures tda1004x_config in saa7134-dvb.c
have a entry .gpio_config. Please change this to TDA10046_GP01_I or try
card type 81.

Good luck
  Hartmut
