Gecko OS oddities with the latest devkitppc/libfat/libogc

[MP2E]

Greetings, newbie to Wii development here. I own a new Wii with the new Wii remotes so I've been used to recompiling my own homebrew for some time now, but I've run in to a very strange issue with my patches to Gecko OS. It just hangs after "SD Codes Found. Applying" and seems to corrupt some of the graphics on-screen. After that, the Wii requires a hard reset and all the controllers are instantly disconnected. I've checked everything I've modified several times and because it doesn't give me a stack dump or anything debugging it has proven very tricky.

Any pointers in the right direction, even if only some tips to help debug the problem is appreciated
