Hi,

When trying to boot a 2.6.16 kernel (kernel.org sources with the only 
patch being for Reiser4 FS support), the kernel dies on bootup on my 
dual-processor Alpha system, with the error "Unable to handle kernel 
paging request at virtual address 0000000000000058".  The system is an 
API CS20 with 2 833MHz 21264b processors and 1 GB of RAM (8 x 128 MB). I 
have attached all of the output from the serial console, including the 
error message, along with a gzipped version of the .config used to 
compile the kernel and the output of "lspci -vvv".  Looking at the 
kernel output prior to the kernel panic, I noticed it only activated one 
processor even though it probed two.

Here is the output of the ver_linux script:

mantheren:/usr/src/linux-2.6.16# sh ./scripts/ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

If you need any other information or would like me to test anything, 
please let me know.

P.S.  The system is running a home-brew "distro" with everything 
compiled from scratch, and running a 2.6.15.6 kernel it has not given 
any problems even through recompiles of all of the installed software 
(glibc through firefox).
