I don't know the performance impact. You can find the command in earlier comments, but you basically want a variation of: /sbin/ethtool -K eth0 gso off gro off tso off
with your network device substituted for "eth0". If you simply run this manually after boot up, rebooting should turn it back on (well, should restore default behaviour). Otherwise you can probably revert with: /sbin/ethtool -K eth0 gso on gro on tso on -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1766377 Title: Intel Ethernet I218-V [8086:15a1] Subsystem [1043:85c4] detected Hardware Unit Hang Status in linux package in Ubuntu: Expired Status in linux source package in Bionic: Confirmed Bug description: With Bionic kernel 4.15.0-15 and 4.15.0-17 I am experiencing periodic hanging of the LAN connection.
