Heh, a few years back I spent like a month diagnosing a problem where the fix was two hexadecimal characters on the same line.

Some bespoke hardware was dying by kernel panic within ~30s of starting up, after a bunch of library/kernel/vendor-drivers upgrades. I don't think a month is too bad considering I had zero C/C++ experience (yes, I pointed this out to them repeatedly), each recompile/test/lab-install cycle was really long, and the problem wasn't really in the kernel at all, but actually a pre-existing collision/corruption of the memory space where the kernel was being loaded.
