[Lustre-discuss] configuring lustre network get kernel panic

Wed Apr 23 06:19:50 PDT 2008

Hi Christian,

We had the same problem a few months ago. See bugzilla 14988 for all the 
details, and comment #21 
(https://bugzilla.lustre.org/show_bug.cgi?id=14988#c21) for the solution.

Regards,
Sebastien.
