Hi - I just patched a couple of servers and noticed quite quickly very slow throughput on the network and these kernel messages
Nov 22 09:03:23 vuh-lb-webdev04 kernel: ens192: bad gso: type: 1, size: 1448
The network is virtio on nutanix
The kernel was 5.14.0-503.14.1.el9_5
I have put the kernel down to a previous version and its ok now.
grubby --set-default /boot/vmlinuz-5.14.0-427.24.1.el9_4.x86_64
I’ve had the same problem with Nutanix VMs and 9.5
The workaround with turning ‘rx-gro-hw’ off is fine for installed VMs (upgraded from 9.4) - but doesn’t help when network installing 9.5 … I’m trying to find if there is a workaround for this ?
I’ve managed to find a hacky workaround to this problem when PXE installing 9.5 using the virtio_net driver - which involves adding the ethtool workaround into the PXE install initrd.img - if anyone is interested, the following script can be run to create a new/hacked PXE initrd.img from the original:
Any update on this? I see 9.5 came with kernel 5.14.0-503.14.1 and now 5.14.0-503.15.1 is available, but the release notes don’t seem to specifically address this particular issue. If I need to wait for 5.14.0-533, is there any ETA?
