okay, thanks. But I looked wrong. It were only the bootloader flash
parameters that were set. Just before starting the kernel the routine
enable_caches(0, 0); /* also flushes caches */
is called, which turns the I-cache and D-cache off.

It's very possible - the init code isn't setup to handle the "cache on"
case, and it'll probably cause it to crash or do other random things.
