July 7Jul 7 Author here are the diags... stongly suspect sriov/vm as the root cause... but hard to tell...I have been trying for months... to get sriov to work for cachyos guest... but no joy.I did notice starting/stopping a vm tends to to trigger the error....buckyu-diagnostics-20260708-0841.zip Edited July 7Jul 7 by bucky2780
July 8Jul 8 Community Expert These errors by themselves are typically harmless, and I'm not seeing anything else relevant logged. Are you encountering any issues with the NFS mounts?
July 8Jul 8 Author mounts are ok... I am glad this is benignI have been getting some recent freeze ups of my server. Happens occasionally... I suspect vm's that are sriov enabled, so rolled them back to virtual gpu for the moment. Win11 works ok with sriov... but very unstable otherwise.These nfs busy errors happened around the same time.... which is why I am looking more deeply into it.cheers
