Please try this one (with CONFIG_EARLY_PRINTK=y). I've compile tested but
have no hardware here to run it. This patch should fix a couple of bugs,
though perhaps not the one that is causing the unexpected irq (?)
As I recall the crash is a bit unpredictable, but I could reliably trigger
an unexpected interrupt with a serial cable connected to a terminal
emulator with hardware handshaking by bringing the emultator online when
the kernel first begins to execute.
