Both GPUs are v2.0 cards, and v3.0 slots are supposed to work with v2.0 cards. I found that by going into the BIOS and restricting PCIe slots 2 and 5 to v2.0 speeds (5 GB/s) instead of the default v3.0 supported by the Z420, the GPU would run reliably.
r284665 causes MSI problems -> ahcich2: Timeout in slot 11 port 0 Hello, r284665 causes ahci(4) to fail with timeouts when using MSI (the default). 'hint.ahci.0.msi=0' is one way to make ahci(4) working with r284665, but obviously not the desired solution, it just disables usage of an MSI. AHCI detection problems - ZFSguru As I see there is no DIPM power saving enabled by default in loader.conf so I think power saving is regulated by other features. What I would like to say is if somebody has CAM errors on an AMD SB7x chipset should think about explicitly disabling AHCI power saving as I suggested which may take you 0.8W but you get a stable system for this small price. freebsd-bugs - [Bug 201194] Kernel: ahcich: Timeout in slot ACB: ef 02 00 00 00 40 00 00 00 00 00 00 Sep 30 13:26:08 trillian kernel: (ada0:ahcich0:0:0:0): CAM status: Command timeout Sep 30 13:26:08 trillian kernel: (ada0:ahcich0:0:0:0): Retrying command Sep 30 13:26:29 trillian kernel: ahcich1: Timeout on slot 18 port 0 Sep 30 13:26:29 trillian kernel: ahcich1: is 00000000 cs 00000000 ss 00000000 rs [Bug 213083] after zpool import ahcich3: Timeout on slot

This isn't guaranteed to produce a timeout, since 192.0.2.10 could (although its not likely) be a real host, and like 127.0.0.1, it could return "port unreachable" immediately upon querying. You don't need to pick a host that you're sure isn't running DNS (like your nslookup command checks) you need to pick a host you are sure won't respond at all. cisco - slot vs sub-slot? - Network Engineering Stack Exchange The x800s also have built-in WIC slots. So if a 2 port serial card is inserted into the first built-in WIC slot, the interfaces are number Se0/0/0 and Se0/0/1. If the second built-in WIC slot is populated with the same 2 port serial card, the numbering is Se0/1/0 and Se0/1/1. The next slot available on an x800 would be the first network module ...
