SE/30 - 7.5.5 Bus error when using restart or shut down

[Bolacore]

Hello there - I recently tried installing 7.5.5 on my SE/30, and after 23 something floppies it installed just fine. Everything works correctly on it, but I noticed if I use the Shutdown or Restart options in Finder it bombs with just "bus error". The restart button on that message works just fine. If I boot it back up with my 7.1 floppy, Shutdown+Restart work just fine. Any idea why it would bomb like this? Not sure if the install was a bit corrupted, or if there's some other issue. Board is recapped and in good shape.

Does it do it with extensions disabled?

Mine works fine with 7.5.5 so i would say extensions as well

I get this issue with MODE32 + macOS 7.5.5 + 32-bit memory addressing on. For me, the Restart button does not work.

My SE/30 did not like the 3-chip (or was it 4?) SIMMs I had in it (8x4MB). Try some 8-chip SIMMs if that's your situation. Same random bus errors  went away for me.
