Jaromir,
Since you committed your exit-path patch on 2004/01/04 all my ARM systems
have started to hang during bootstrap.
Investigation using a Multi-ICE box shows that the vectors page is getting
unmapped (on all my machines the vectors are at VA 0x0, which puts it
notionally in user memory, although it's really a kernel page). Loosing
the interrupt and fault vectors is obviously somewhat fatal to the health
of the machine.
Have you any idea what might be the cause of this change in behaviour?
R.
