Terry:
What is the purpose of your exercise? We are not going to update to pre8
since we know it is broken. We are reluctant to go to pre10 since neither
PowerPC nor Alpha work at this level. Our goal is to provide a balance between
newer kernels and stability. If you want to experiment with the RTLinux code
on bleeding edge kernels, that's great.
Please also note that RTLinux Alpha has been tested by FSM on DS10/Tsunami only.
The pc164 is likely to need some work because, among other things, it has
a different motherboard control chip.
