Subject: OOPS in inotify code, kernel 2.6.31.6-162.fc12.i686.PAE

Hello, when I tried incrond inotify daemon, I found this in system log:

In addition to things above: System is Fedora 12 i686 linux, Core2 Duo E8200, 4GB RAM,
  ext4 fs on root (where I had inotify paths - they was somewhere under /home/).

Or report to Fedora's bugzilla is more appropriate?

Thanks, Franta Hanzlik
