In light of this, I'd like to propose that we turn off DEBUG_STACKOVERFLOW in Fedora, at least on x86/4KSTACKS. I think it does more harm than good; the warning is going to turn deadly most of the time.
Sorry for butting in... but isn't disabling STACKOVERFLOW the wrong answer to this problem? Does anyone see any reason why both sprint_symbol and __print_symbol shouldn't use dynamically allocated buffers instead of wasting stack space? *
I think the reason is that kmalloc can sleep, and those functions may be called from code that can't sleep.
