i was having the same sorts of corruption problems(not inode corruption so much) but of the unexplained kernel exception and "what's this doing on the SCSI queue?" message variety using the fast and wide ncr53c825 board.
high activity seems to be a factor to the 1.7 driver. a tar from the hard drive to a 4 mm dat tape driven by the same board could reproduce strange results almost every time.
roudier's 1.8 version is a quantum leap is stability and performance for me.
it also has some neat statistics in /proc.
see my attached driver boot messages.
