A mixed kernel can boot without panic (tested today).

The panic is avoided when CONFIG_ARM_THUMB=y is removed.

See thread "[PATCH] ARM: reinsert ARCH_MULTI_V4 Kconfig option":

I got the impression from Guenter Roeck's review, that it doesn't belong there,
maybe I was too quick to remove it?

See thread "[PATCH] watchdog: Add MOXA ART watchdog driver":
