[U-Boot-Users] If I-cache enabled, the system gets unstable

Mon Jul 17 17:06:06 CEST 2006

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)
