What about panics in the storage/FAT code?
What about panics in IRQ mode?
What about memory corruption crashes?
I don't think there is a reliable way to access storage after a panic.
Doing this reliably would probably require a full crashkernel, which
wastes even more memory.
OTOH we could write a memory dump to disk that way :)

Just my 2 cents.
