I encountered the same problem with 2010r1-rc5 release.
When the AD73322 cascade is configured for either sport 0 or sport 1 the
problem appears to be a while loop at line 775 in the snd_ad73322_configure
function of ad73322.c.
Code snippet:
status = bfin_read_SPORT_STAT();
while (!(status & TUVF)){
udelay(1);
status = bfin_read_SPORT_STAT();
SSYNC();
}

The problem that I encountered was caused by the 'PF pin for AD73322 Chip
Select' not being set correctly on a custom AD73322 board.
