The only problems I had were SCSI timeouts, and that's in no way new for
Falcon users, right? The only surprise was that high timeout rate also means
data corruption, from all I could see. At first I though that ext2 filesystems
written on other hardware were incompatible with the AB040 (bus sizing
problems?), but the filesystem written on AB040 could be read on a Mac, no
problem there.

Could you be a bit more specific?? Linux maps the hardware addresses in a
separate range in memory, as non-cacheable and serialized. How could the
dhardware registers be cached?
