Previously, I tried this method, but it didn't work for me: http://serverfault.com/questio…tected-hardware-unit-hang
Then, I tried to disabled C1e state, using the kernel 4.5.3 , and update the nic driver, but error persist.
Basically, OMV suppose to auto shutdown/wake up on daily basis according to cron job, but it freeze upon shutdown.
Therefore, I have to manually shutdown every night.
Update: I've tried the new kernel but no luck.
I even using this parameters: ethtool -K eth0 gso off gro off tso off
Not sure if this matter, but I notice that this does not happen frequently when I'm using HDD back then.
Since I'm migrating OMV to SSD, this happens frequently.
