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.
Can you please try a pristine v3.1? The only relevant differences are the
conversion to the genirq framework and the Atari SCC driver.
If that works, I guess it's a regression introduced by the genirq conversion.
Then you can bisect between v3.1 and m68k-v3.1.
BTW, in between 9fa434585e5f6cfeae685505b4cd8465dbab1dff ("m68k/irq:
Add genirq support") and 971ae31663e817a5e5b673d30c7652d9160145f0
("m68k/irq: Remove obsolete m68k irq framework"), genirq support is a config
option that can be turned on or off.
