Was testing the patch on arm server. Didn't see crash there but observing timeouts and error

At your end do you still face similar situation on arm server ?
Yeah, I see that as well even without enabling the IOMMU.

I figured that it was a card FW issue as I have been using what I got
out the box, and I have no tool to update the firmware on an arm host.
It seems that SSP and STP commands are not completing for some reason,
