Network drops eth0: Reset adapter unexpectedly

Recommended Posts

Hi All


I have recently installed unraid and everything is good apart from I keep on getting random network drops.  I get the error message "Tower kernel: e1000e 0000:00:1f.6 eth0: Reset adapter unexpectedly" and then I lose network connectivity for a minute while it sorts it self out.


Any help would be appreciated.

I was able to resolve this as well by disabling the same features on the NIC via the terminal:

ethtool -K eth0 gso off gro off tso off

...and by adding this to my Syslinux config:


I followed this thread: https://serverfault.com/questions/616485/e1000e-reset-adapter-unexpectedly-detected-hardware-unit-hang.  Since disabling these, I haven't had the issue reoccur.  I believe they were reset (back to enabled) when I installed an Unraid update, however, so I may need to add them to a reboot cron job to make it persist.  


I don't know which change was actually the one that fixed it, but I'm too lazy to re-enable one at a time to test.
