dmesg (kernel 5.5-rc6+, INLINE KASAN, PowerMac G4 DP)

However I might have gotten a hint where the stack is clobbered. The IRQ stack
overflows sooner or later (CONFIG_DEBUG_SHIRQ=y might have brought that up?),
which causes all sorts of problems.

I'll attach the dmesg here but I can open a new bug if this is more suitable.
