Kernel Panic while using Solarflare SFN5122F under load.

[meanmean]

Hi, I am using a FreeeNAS-11.1 U2 with an SFN5122F. When I mount a samba partition and start some large transfers I end up with a kernel panic:

Code:

panic: P2ROUNDUP(addr + 1, etp->et_enp->en_nic_cfg.enc_tx_dma_desc_boundary) >= addr + size										 
cpuid = 2

This doesn't seem to be related to any obvious issues such as CPU Temp etc... and I have no issue with the Realtek interface on the NAS.

Any ideas?

Well, the Realtek isn't helping as it won't be able to handle load (replace it with one of the inexpensive Intels recommended in the Hardware Recommendations PDF).

What are the hardware specs for this system?

Thanks for the response,

The mention of the Realtek was simply to note that just accessing the system didn't cause any issues. The primary interface for file sharing is through the SFN5122F.

The NAS specs are:

i5-2400 with 32GB of DDR3
Motherboard: h67a-g43 (b3)
4x WD 2TB Greens
SFN5122F Direct Attached (Passive Copper,10GBE,MTU=9000) to a 2012 Mac Pro (SFN5122F) and a Linux Box (mellanox connectx-2).
Realtek 8111E

All connections are on separate subnets. Only, the Realtek interface has access to the internet through the LAN.
Running SMB, AFS, and a jail with plex.

Note: This seems to be an issue for other Solar Flare Cards: https://forums.freenas.org/index.php?threads/kernel-panic-on-11-1-with-sfn5162f.59443/but is fixed in FreeBSD upstream.
