I assume you mean "Pass1" and "Pass2" when you say "stage1" and

Could you run the following command, and send me a pointer to it:

e2image -r /dev/hdXXX | bzip2 > hdXXX.img.bz2

(Replace /dev/hdXXX and hdXXX.img.bz2 as appropriate.)  See the
e2image man page for more information, but this will create a
metadata-only dump of your filesystem, and then compress it.  It will
be very useful for me to figure out what might be going on.  

Something else that would be useful would be to try running e2fsck
with the "-C 0" option, and let me know what the progress bar does
when it reaches "stage 2".
