Your problem is more likely due to unreliable RAM.

cramfs (due to decompression) works RAM a lot harder than romfs even if
both are in RAM.  If your romfs in in ROM,  the RAM is not working
anywhere near as hard ;-)

Also,  cramfs's decompression actually checks things are making sense.
romfs does not.
