Hi

just reading the thread about "Emulation of the TT second MFP", I see a 
message from Eero :

"
Linux assumes that if setting SCU interrupt mask doesn't generate
a fault, it and VME are both present.  To get TT booting (using IDE)
with Linux, I had to change its access to cause a fault.
"

Eero, could this be the reason Uwe is seeing an error now ? (note that I 
didn't try to replicate this myself yet, so this might be completely 
unrelated)
