I guess the firmware is not loaded correctly.
Please revert av7110.c to the state from CVS (or from 1.1.0), and apply
the patch below:
(u32 is 64 bit on amd64, but AFAIK uint32_t should always be 32bit
according to ISO C99)

If that doesn't fix it (because uint32_t is 64bit...) we need to do
some more work.

If it doesn't work, can you run the following program and post its
output:

-----
#include <stdio.h>
#include <stdint.h>
int main()
{
	printf("%u\n", sizeof(uint32_t));
	return 0;
}
