I moved forwarded and a server started rebooting while loading the kernel current kernels. I isolated it to the lpfc driver. Upsteam kernels tried so far: 3.6.34-rc1 3.4.33-git15 With these kernels I see the following when the driver loads: " [ 276.643991] Emulex LightPulse Fibre Channel SCSI driver 8.3.9 [ 276.643996] Copyright(c) 2004-2009 Emulex.

I get a hardware level pci fault and my box reboots. My FW has been constant during this at 282a4 (current I believe) and lspci reports the card as 1a:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02) 1a:00.1 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02) The system is a 2 socket Intel based server IBM x3550m2. I forwarded ported some of the older versions of the driver 8.3.7 and 8.3.6 and that didn't not fix the issue, I am not convinced it is a direct driver change that is causing this. I also tried "lpfc_use_msi" and "lpfc_sli_mode" modules options without any affect on behavior. Then I started testing whole kernels, .config file remained as close as possible. After some boots it seem 2.6.33-rc8 and before works. It is a relatively small window of change and I am still digging but I thought I would post and see if there were any ideas or suggestions out there. Anyone seen anything like this?
