2.5.14 fs oopses

[Petr Vandrovec]

Hi,
  2.5.14 kernel decided to commit suicide after I tried to remove 450MB
file streamer (using bttv) just created. Kernel is tainted due to
VMware's vmmon, but vmware (even X) was not started this time since
boot.

  fsck after reboot found just one unattached inode, still consuming
450MB (exactly 914600 sectors). And no, I do not remember doing
anything with '/41/' or '/14/'.
