Hmm --- I've some trouble with 2.0.20 too ... and absolute no trouble
with 2.0.0, 2.0.9, 2.0.11, and 2.0.18

2.0.20 will die on first disk access (partition check or start of
/sbin/init) within an oops

This oops occures on an i486-PCI-System with saturn II Rev 4 (without bug),
ncr53c810, and an amd586-p75 ... maybe I should check this with my old
amd486dx4-100.

On other systems on work (all i586) there are no problems with ncr53c810
and 53c7,8xx driver .... timing problem?
