Shapeshifter3.11 + OS8.1 + Apollo4060 = fail?!

[Ratte]

Very strange problem here ...

My setup works perfect, but "only" OS8.1 fails.
All other OSes from 7.1 up to 8.0 are working.

Setup:
ShapeShifter 3.11
MacOS 8.0
Quadra900 ROM-File
A4000 + Apollo4060 128MB / 68060 rev.6

From my memories, OS8.1 worked fine on my MKII060 (years ago ...).

Is this problem known?
Any workarounds or hints?

Thanx in advance.
