Yes, but not for the same reason as in other cases.

The firmware (at least the application part, the firmware core is
in ROM on-chip) is normally loaded by the driver during init.
The firmware is written through the so-called DEBI-port of the SAA7146
into a dual-ported RAM and from there into DRAM which is used directly
by the AV7110.
At the beginning of the firmware download routine the DEBI-port writes
some bytes to the dual-ported RAM and reads them back to test the
DEBI-port. This basic test failed in your case!

This is not good and indicates a hardware problem, either with
the SAA7146, or the dual-ported RAM. 

Since all those cards are really identical I also cannot think of
another reason for this problem, like e.g. timing problems or use of 
different components, etc.

Did you try this card using Windows with drivers from Galaxis? Does it work there?
If not I would strongly suggest to have a talk with the person you
bought it from. You said you got it at ebay?
