That sounds about right. This type of issue is sprinkled throughout. I'm on a tight deadline for another project, but I will refer you to another developer who is currently working on a maintenance release of that driver. I'll see if we can add porting to PPC to the scope of the next release. BTW, I am the original developer, so all bugs can be blamed on me! If you need help digging through the driver code, just let me know. > Of course I have to try that out first (I'm still home now), > and let you know if that produced any results.

We have not started that port yet, but I'm sure we will run into the same issue. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
