Hi Zeng,
This appears to be a different issue. I can't reproduce your problem
with /proc. I notice you are not using the recommended versions of
binutils, gcc and uClibc, so it is possible the patches have not worked
correctly. Do you get the same problem if you use binutils 2.16.1, gcc
3.4.4 and uClibc 0.9.28.3?
I can reproduce the problem with "umount /proc". However I'm not sure
that unmounting /proc is a good thing to do to any Linux system. So this
may just be Linux getting completely confused.
I have reopened your bug in the tracker and assigned it to Rich D'Addio,
who is the local Linux expert.
ATB,
Jeremy
