A long time ago (2.2.13 or so), I could not use another card on the 6500 for very long with the de4x5 driver as well. At that time, Paul provided a patch for the de4x5 driver which fixed the problem. He also described the issue as a cache coherency problem.
Yes, paul's patch is what I'm talking about.
Well, I wonder if that was the fix that Paul put in. Some time ago (early 2.4) I tried the de4x5 driver with this Farallon 10/100 card but it worked even more poorly than the tulip driver of that time did.
Yup.

Try defining CACHE_ALIGN to CAL_32LONG, and DESC_ALIGN to u32 dummy[4] (as in the commented out example).I will look at the de4x5 code again and try this. It's all vaguely familiar to me... Thanks much!
That should be the same patch paul did. Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
