Thanks. Probably
destroy-the-dentries-contributed-by-a-superblock-on-unmounting.patch went
wrong, possibly an interaction between
destroy-the-dentries-contributed-by-a-superblock-on-unmounting.patch and
ro-bind-mounts-*.patch.
If you have time, please:
- Confirm that it is reproducible.
- If it is, test http://www.zip.com.au/~akpm/linux/patches/stuff/rf.bz2.
That's a patch against 2.6.17. It's basically -mm4, with
ro-bind-mounts-*.patch removed (and with x86[_64] generic IRQ wired up).
If that fails in the same way, we know that
destroy-the-dentries-contributed-by-a-superblock-on-unmounting.patch is
the bad guy.
