For now I can't tell what is wrong. But I want to update the firmware on the card to take another shot at it. Since this is an ARM based server, I will have to find a way to update the firmware. IIRC our tools are mostly x86 based. So I am looking around. I will update you soon. Thanks Ajit On Fri, Mar 5, 2021 at 2:06 PM Ajit Khaparde wrote: > Hi David, > That's a good idea.

David,
I did spend some time on this. For now I can't tell wh= at is wrong.
But I want to update the firmware on the card to take another s= hot at it.
Since this is an ARM based server, I will have to find a way to u= pdate the firmware.
IIRC our tools are mostly x86 based. So I am looking aro= und.
I will update you soon.

Thanks
Ajit

Hi Ajit, Juraj,

For simplicity, we will keep the funct= ional and performance testing disable during the weekend.

In this way, you will have no testing interfere with you during troublesho= oting.

Then we will rerun all the jobs that are skipped.<= /div>

Please let me know if you have any questions.

Best,
David
