Hi

I noticed that in the added patch you write "Avoid freeze on TT / 
MegaST*" ; note that it's only on MegaSTE, not MegaSTF, so ST* might not 
be the correct description.

also if you send the patch to the linux m68k people for inclusion, 
better fix would be to set "tt_scu.sys_mask = 0" instead of adding a 
default handler for the VBL interrupt (as on Falcon)
