I've found the reason for problem, I've had with the 2.1.x kernels for quite
some time. My problem was, that a simple main() { for (;;); } stopped
the whole machine. The reason for my problem is a bug in gcc (or two to
be exact). Because I couldn't compile isdn_common.c with -O2, I've changed
the CFLAGS in Makefile to compile only with -O. This triggers another more
unvisible bug in gcc, when compiling arch/alpha/kernel/irq.c, which causes
the problem with the hanging.
At the moment I'm running a 2.1.102 kernel compiled with -O and irq.c with
-O2. And it works.
I'll try to find the function in irq.c, which gets miscompiled with -O.
Thomas.
