--- Comment #7 from Chen, Fan (farrah.chen@intel.com) ---
I also tried the option you mentioned "x-msix-relocation=bar5", still the same
result, host crash.
In addition, according to the host serial log in description, the error devices
is b7:00.04 and b7:02.00, and the BDF of my X710 is b8:00.0.
I checked pcie topology of my system:
+-[0000:b7]-+-00.0
| +-00.1
| +-00.2
| +-00.4
| \-02.0-[b8]--+-00.0
| \-00.1
So the AER errors are reported on the bridge (b7:02.0) of the assigned device
(b8:00.0), and a device (b7:00.4) sibling to the bridge.
