Looks like the error checking is the issue. Always knew that was a bad idea :) I've just sent a patch to improve the diagnostics here which might help a bit, though I realise now with some of my debug I need to send a v2 :/ .
On my system there's only one mapping failed, but it's for one of the VIC mappings which is rather unfortunate. The error is there because the VIC is returning -ENOTSUPP to skip invalid IRQs which doesn't immediately seem like an awful thing to do for generic code like this.
