sometimes, I experience data corruption.... but it could exists more than
one reason for it...

at first I am not sure @ which rate my l2 cache really runs... maybe someone
of u know if its 2:1 or 3:1...
I just know that its a pm7300 with a g3 update with 512 kb? Your help is
greatly appreciated.

and secondly I use a pci promise udma100 controller...which is not 100% sure
that it works reliable on netbsd/macppc. Does anybody know if there exists a
ata controller that works on netbsd/macppc reliable?

And finally? Is it just -current- that causes this data corruption? is
somebody experiencing the same?

Regards
Andreas
