Detected Hardware Unit Hang.

tinh_x7 · Apr 15th 2016

Hi guys,

Lately my OMV couldn't shutdown frequently because one of the NIC is hanging upon auto shutdown on daily basis.
It happens one or twice a week.
I've tried both kernels, and they both have the same issue.
Regardless whether the NIC is connect directly to the router or indirectly to the router (via UPS), error persist.
I'm currently using bonding: balance-alb.
My integrated NIC is my primary.
The screenshots are the error messages that appeared upon auto shutdown of a cron job.

OMV: v2.2.2

Tried with the above solutions, but it didn't work.

I've tried kernels: 3.16, 3.2.0, 4.5.1, but no luck.
