https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D240944 --- Comment #13 from Kevin Bowling <kbowling@freebsd.org> --- (In reply to Ace from comment #12) > ecap 0001[100] =3D AER 1 0 fatal 1 non-fatal 2 corrected You have some fatal PCI errors occurring on the card, and that looks consis= tent with the other pciconf reports.. just to start with a low effort guess can= you try disabling PCI Link Power management (ASPM) and/or AER (advanced error reporting) in the system's firmware and see what happens? Beyond that there are a number of relevant errata we may need to check off = in the driver to see if we are missing some mitigation http://iommu.com/datasheets/e1000-datasheets/82571eb-82572ei-gbe-controller= -spec-update.pdf the above two firmware changes stand out to me as eliminating some possible issues. --=20 You are receiving this mail because: You are the assignee for the bug.=
