Hi,
I'm also having this issue on the same model of motherboard except that I'm
running on a 100mbps network. I would get watchdog timeouts and TX
descriptor errors more frequently then not even there is minimal network
activity i.e. just SSH in the box. I'm running 8.1-RELEASE.
mskc0: <Marvell Yukon 88E8056 Gigabit Ethernet> port 0xe800-0xe8ff mem
0xfebfc000-0xfebfffff irq 18 at device 0.0 on pci2
msk0: <Marvell Technology Group Ltd. Yukon EC Ultra Id 0xb4 Rev 0x05> on
mskc0
msk0: Ethernet address: 00:ea:01:15:c6:52
miibus0: <MII bus> on msk0
mskc0: [ITHREAD]
msk0: link state changed to UP
msk0: watchdog timeout
msk0: link state changed to DOWN
msk0: link state changed to UP
Having TSO and MSI disabled in sysctl and loader respectively does not
appear to have any improvement.
Additionally the kernel would panic when booting, this happens 1 in every 2
tries:
Aug 18 01:35:26 kernel: mskc0: <Marvell Yukon 88E8056 Gigabit Ethernet>
port 0xe800-0xe8ff mem 0xfebfc000-0xfebfffff irq 18 at device 0.0 on pci2
Aug 18 01:35:26 kernel: msk0: <Marvell Technology Group Ltd. Yukon EC Ultra

Aug 18 01:35:26 kernel: msk0: Ethernet address: ff:ff:ff:ff:ff:ff
Aug 18 01:35:26 kernel: msk0: No PHY found!
...
Panic message ensues
This happens regardless whether the cable is plugged or not.
Normal booting would be like this:
Aug 18 01:35:26 kernel: mskc0: <Marvell Yukon 88E8056 Gigabit Ethernet>
