I use 2.4.18 on my SS20 (2 Ross Hypersparc 125 MHz, 196 MB).
Sometimes (not very often) the machine freezes for a while when X is starting
during the boot process (network alive at that moment). But overall, it works
fine.

Hmm. I recently baught a VSIMM for the onboard high resolution graphics. With
that module installed, I have the same problem: everything ok in the
beginning, but when init starts ...
When I remove the module and connect the monitor to the SBUS graphics, the
SS20 works fine again. And when I remove the SBUS card and install the VSIMM,
I get an SBUS error when init should start.

I did not try that.

Did not test kernel 2.2.

Which graphics on your SS10? Might that be a hint?
