Page Fault during Boot with Mellanox ConnectX

[bimini]

Hi Everyone,

I wanted to Speed up my Network Connection between my Nas and my main machine so i got old Dual Port IB Cards back home from work.

When insert one into my Nas (Freenas 10, Core i3-2100, 8GB ECC Ram, Supermicro X9SCM, USB Flash drive for Boot, 2*512 Gb SSD Mirror, 4*4TB HDD RaidZ2) i get the following error:

I don't know much about BSD but from my understanding either the Kernel module breaks something or something goes wrong with the DMA Access of the Controller.
Or is it that my USB Drive has got a bad sector which just matters if this Module is loaded. After i removed the IB Card it worked as usual.

Is there a way to get the System to boot and fix that issue later?
Is it important to know the specific Typ of that Card. We have a pile of them laying around at work since we are moving to QDR and i just grabbed two.

Thanks

Bimini

Image wasn't correctly inserted or something.

Anyway, it's likely to be a real bug with limited possibilities for a fix. Try a fresh install on new media and see what happens.

Hi,
thanks for your reply.
I reinstalled Freenas an at that Point moved to Freenas 11.
Sadly it didn't changed much. It seems like there is an Issue with the Driver. Is there a way to disable that kernel module?

At first it seems ok. The ports are discovered.

But then it crashes again

Thanks in advance
Bimini
