in kernel-2.6.32-71.4.1.el6

Comment 4 Gris Ge 2010-10-15 07:23:07 UTC
Cannot reproduce this issue with "Emulex LPe12002-M8".
It's firmware version is :
1.11A5 (U3D1.11A5), sli-3

Kernel version: 2.6.32-71.el6.x86_64
Reboot 5 times, no lpfc kernel panic came out.

As Bug #634703 spot out:
>Emulex believes there is exposure to this issue in large SAN environment where
>the device discovery process could see delayed responses which result in iocbs
>being queued.

Do we need a large SAN environment to reproduce this issue?

Very likely you do.

I added 20 more SAN disks to the configuration and did a one hour reboot cycle for the system.
