Ever since updating to Fangtooth and setting up my ethernet bridge I’ve had this weird error that happens a couple times a week that leaves my server in an unusable state.
I keep having this error happen.
“eno1: Detected Hardware Unit Hang”
Bare metal, and it’s running on a GA-X99-UD4.
I didn’t have this issue before Fangtooth and I’ve been forgetting to post about it as it usually happens when I’m out of the house and have to remotely restart using my KVM.
I’m sorry to say, but if you had a hardware failure causing system crash, then options now are to try & experiment and see if replacing parts.
If it is your ethernet adapter and it isn’t built-it, then I’d slap a different one into a PCIe slot and test. If it is built-in to the motherboard, I’d try to disable it in BIOS and slap a different card into a PCIE slot.
I’m not sure what else to recommend other than maybe rolling back to a previous version if it was stable.
something else to keep in mind is that motherboard Ethernet on non-server boards is notorious for improperly being cooled (ie, not at all).
yes, even modern gigabit chipsets w/ all their cost reduction can overheat with sustained workloads. though it only got worse in the 2.5Gbe generation where even moderate workloads would overheat and crash NICs.
