Fair enough, at least if you are bisecting/debugging... but then you are recompiling multiple times anyway and nobody wants to and nothing stops you from keeping CONFIG_PANIC_ON_OOPS off while doing so. However, that's not the average use case and that doesn't mean it must be off for everyone, it will remain "better safe then sorry" by default for the reasons i pointed out. cheers, Levente
