[Lustre-discuss] Kernel Oops lustre 1.6

[Karen M. Fernsler]

Hi,

We're having a little problem with getting lustre-1.6.4.3 up and running on a kernel org 2.6.18 kernel running over rhel4.  When we try to mount one of the filesystems the kernel panics.  The ost and mds in question are still running lustre 1.4.10-1 -- should we expect that to work with a 1.6 client?

Has anyone else run into this?

The kernel panic is below -- thanks for any input.
