tux kernel panic

[Tom Jin]

Hi:

This problem has been reported already.
tux crashed with symbolic links in FC3.

Here's my tests:

1. Default Fedora Core 3 installation. Symbolic links located in both reiserfs and ext3 partitions,
   kernel panic.

2. FC3 with kernel 2.6.10 and tux3-2.6.10-rc3-A7. Same panic.

Some of dmesgs:
