Kernel Panic - Confirm I'm not retarded before I open a bug report

[Bazant0r]

Hi all,

Looking for some confirmation that I've either done something wrong or there is something obvious that I am missing. My setup:

2X Supermicro 4U Chassis ( 24Disk and 45 Disk external )
MB: Supermicro X10DRH-C/i
CPU: 2X Xeon 2.4 Ghz 2460 v3
MEM: 256GB
RAID: LSI 3108 MegaRAID 6.22.03.0 - FW 24.7.0.-0026

Drives:
1x: 32GB Sandisk USB 3.0 ( boot drive ) - hd0
4X: KINGSTON SUV400S 400GB ea
4X: INTEL SSDSC2CT24 240GB ea
16X: WDC WD2003FZEX-0 2TB ea
24X: WDC WD2003FZEX-0 2TB ea - Connected via external SAS onto LSI RAID

4x Kington act as single L2ARC cache device and 4x Intel acts as a single ZIL device.

20x vdevs consisting of ( 2 x 2TB devices )

2 X RJ-45 10G
4 X 10G SFP+ - Intel X710 chipset ( Installed Oct 2016 )

System has worked well since Dec 2015 until now.

Two different issues that may or may not be related. Shortly after updating from 9.10.2-U1 to 9.10.2-U2 and updating the network interface running on the X710 ( created a 4 NIC LAGG to a Dell S4048-ON switch running FTOS 9.11.0.0P4 ) FreeNAS kernel panic'd and now no longer boots. The boot sequence attached is the end result. I can re-install FreeNAS, but on next boot I get the same error.

Has anyone else had the same behavior with the X710 adapters or is it something else entirely? Feel free to sharpshoot, I'm sort of at a loss. I really don't want to remove the X710.

Ugh. At the very least, use the mrsas driver and ensure all your drives are direct-attach (daX).

4 X 10G SFP+ - Intel X710 chipset ( Installed Oct 2016 )

It's quite likely that FreeBSD 11 has a newer driver that helps. You could try the 9.10 nightlies to see if they work better - despite the name, they're using FreeBSD 11 now.

Thanks Eric!

I will definitely use the mrsas driver instead of mfe.

Do you know of any specific reason why it would kernel panic when I configured the LIF and do you think it's likely the USB drive itself that's giving me the issues with the C/H/S errors? I've never seen that before.

No, but it's new hardware and hastily backported early driver... It's bound to have bugs.

issues with the C/H/S errors? I've never seen that before.

Yeah, that's a weird one. To be honest, I'm not familiar with it at all, it looks like legacy garbage (C/H/S mappings gave way to LBA decades ago).
I wouldn't read much into it unless it persists in non-panic scenarios.

Figured out this issue, I'm an indeed an idiot. The X710 card was attemping to load data LUNs, there are none of course so it was failing, hence the C/H/S errors.

Disabling the PXE boot on the x710 solved this.
