If you revert 173808aa9203cf752518acd80fde3c9c910ddd0f ("m68k/atari: SCC
- Mark Atari serial driver BROKEN") you can select CONFIG_ATARI_SCC again,
and get a real serial console.
But first the interrupt storm must be fixed.
unexpected interrupt from 112
That's the vector number, so the actual IRQ number is 112 / 4 = 28, which is
IRQ_TT_MFP_TIMD. Sorry, no clues.
This irq is used for the timer that generates the clock for the MFP
serial port. It should really stay disabled.
Could these spurious interrupts be generated by the debug path, because
I'm now using it to output debug data ?
