Samba 3.0.22 generates a panic error when Norton Ghost (Windows XP) attempts to backup onto my samba backup share.

Here is a trace from the log:

  mediacenter (192.168.1.153) connect to service backup3 initially as user aelbe
r (uid=1000, gid=1001) (pid 11902)

This time it crashed after 26 minutes; it always varies, and sometimes it will even get a few hours before disconnecting.  Windows sees a "Delayed Write Failed" error.  

The Samba server is running on a gentoo distro on a Kurobox.  Of note:  Jumbo frames are in use on this network.

please reopen with more information if this still happens with the latest 3.x release.
