Bug#146883: Kernel compiled for an Alpha SMP is not bootable.

Package: gcc-2.95
Version: 1:2.95.4-9
Severity: normal

-- System Information
Debian Release: 3.0
Kernel Version: Linux big2 2.4.19-pre8-30 #1 SMP Mon May 13 18:01:01 PDT
2002 alpha unknown

Versions of the packages gcc-2.95 depends on:
ii  binutils  The GNU assembler, linker and binary
ii  cpp-2.95       2.95.4-9       The GNU C preprocessor.
ii  gcc            2.95.4-14      The GNU C compiler.
ii  libc6.1        2.2.5-6        GNU C Library: Shared libraries and

If I compile a kernel 2.4.x (I tried with x >= 17) on a Compaq DS20, the
newly compiled kernel oopses in the fontion:
smp_tune_scheduling defined in file arch/alpha/kernel/smp.c

The `switch' statement in that function is where the Oops happens, at
least I believe so: as an experiment I've hard-coded the `on_chip_cache'
variable and commented out the whole switch, the kernel booted up fine.

I compiled with gcc-3.0.4 and the problem disappeared.

Thanks so much for being a Debian devloper!
