apparently this is normal, huh,,, (well, the corruption of kernel panics, not necessarily the kernel panic itself)
the reason why this happens is that on mariko switches (and all switch lites are mariko), on kernel panic the system is forcibly rebooted with a poweroff, the modchip is trying to boot into hekate, and then kernel log is read by hekate
poweroff means ram loses power, which means it slowly loses its contents
