Hi Maurice :)

I've reproduced all your steps and my ramdisk didn't get
corrupted. See below.

Identical commands issued...

Mine is OK. The lost+found is there. I don't suffer any of the
other problems you tell, neither.

Maybe you have bad ram chips, or a damaged mke2fs (unlikely), but
the kernel seems to work OK. I've tested with 2.4.18 and 2.4.17.
