In addition, according to the host serial log in description, the error dev= ices 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 devi= ce (b8:00.0), and a device (b7:00.4) sibling to the bridge. --=20 You may reply to this email to add a comment.
