I'd love to, I just need to know how.
Do I have to send you the compiled kernel? Recompile with debug information
(will take ages to copy :P )?
As long as I can do that, I'll gladly help.
One thing I can safely say is that the halt happens at a later stage than aac0
attachment (it attaches the network cards after that and before the crash), so
I guess it's something interrupt-related, possibly the ld0 recognition (but
since I don't know how to scrollback, I'm quite helpless at that).

Thanks for the help!
