with a current snapshot of Hatari, I cannot boot TOS 2.06 (in ST mode),
anymore. Hatari just hangs with a white screen before even the Fuji logo
appears. GUI is unresponsive, i.e., pressing F12 or AltGr+[Key] does

EmuTOS, in contrast, still boots.

     Fix PendingInterruptCount in CycInt_CallActiveHandler


this is likely the same bug that Eero reported in "freeze in mfp / interrrupt code" and similar to the one I saw too when booting with tos 1.04.

From what I see, it's related to TOS timer D that runs very fast at boot with earlier tos version (timer ctrl=1 data=2) and this messes with new mfp/cycint code. A possible fix is to enable the option in system "patch timer d" while waiting for a proper fix in the code.
