I think you can get filesystem corruption without any obvious crashes
for a while. Note sure though -- my laptop's problem is a region
between LOWMEMSIZE and HIGH_MEMORY which it says is usable, but which
isn't in fact usable.
Have you considered adding Pavel's memory verify patch? It simply
allocs all the pages after memory setup, writes a word to each, and then
frees them again. That's enough to check for ROM pages -- which are the
cause of fs corruption.
