I've gone through 2.4.0, 2.4.1 and now run 2.4.2 on an UP2000, which is ( from the
kernel perspective ) a DS20/20E. I have never encountered any problems with
these kernels in my setup, except those being fixed in subsequent releases.
As a base installation, i run Debian 2.2.0 with some upgrades towards 2.2.2. However,
it is *strongly* recommended following the necessary upgrades to system-level
packages as in ~kernelsrc/Documentation/Changes. Read them carefully and upgrade
the packages in question. They are not available in any .deb format yet ( not even
in woody AFAIK ), so compiling them yourself is recommended.
I do compile my kernels with GCC 2.95.2, however, i use a very conservative approach
to the kernel config.
IMHO, kernel 2.4.x is definitely a plus on SMP Alphas, so you might want to get
that running. In order to give any assistance, some more info is needed:
1. Does the crashing kernel leave any logs ? ( see /var/log/messages )
2. How does your .config look like ?
If you like, forward this data and I'll look at it.
2.4.2 *really* should run on the DS20E with some effort.

Thomas
