[U-Boot-Users] If I-cache enabled, the system gets unstable
I use 2.6.10 with at91rm9200dk, root via NFS - to use ARM native compiler. If I enable I-cache, the system can't compile anything non-trivial. Does anybody know - if it's error in old kernel and I should use 2.6.16, or it's hardware (I have the same kind of errors - segmentation fault - on all identical boards)?
I attached the kernel's config, kernel boot messages in start.log, and errors while native-compile some kernel via NFS. With I-cache disables any native-compilation works well. (I could do without native compilre, but with I-cache enabled I can't run any non-trivial program)

I'm not an at91 expert, but that kind of problem usually points to a memory timing error. Try to relax the timings in your bootloader.
