Basically having searched the forum and google I could not find any solutions, but what looks very strange to me is the line saying:

"NR_IRQS:64"

What should be strange about this? It's perfectly normal (though it was 32 before but we needed to increase the possible number of IRQs to support GPIO IRQs properly). 

Unhandled exception# 0 in kernel mode

Exception# 0 is for reset, so this means the Nios' reset line is asserted (by some external component). You might wan't to check your design.
