Hrm... You should never ever get the gatwick interrupt on a 3400,
since it doesn't contain the Gatwick chipset at all... Or maybe
the code is still calling gatwick what is really OHare II ? What
does /proc/cpuinfo says ?

This is the cascade. It's indeed not a GATWICK PIC then, but rather
an "Ohare II". Probably just misnamed in the code, I may have just
re-used the Gatwick code for OHare II, I don't remember for sure now.
