The 8260 family doesn't use EPIC. It has a custom integrated controller.
Your point is taken that in general someone has to ensure devices and
interrupt controllers are properly initialized. I thought I did this
in the kernel, but perhaps something was missed. Sometimes, a boot rom
can leave something in a weird state (like the I2C for reading an EEPROM)
that the kernel doesn't always use.
