landS Posted December 24, 2018 Share Posted December 24, 2018 (edited) Happy Holidays folks Recently I made a few changes to my rig and now CPU 0 or 6 (physical/hyper) which are reserved for Unraid goes to 100% after some period of time and becomes locked at that percent. The changes: 1 - Swapped a ASM1142/ASM1543 pci card for a ASM1142 card as the 1543 was causing reboot rather than powerdown conditions - This is stubbed out just like the old card (along with a Sata – both for Windows passthrough) via vfio-pci.ids=1b21:0612,1b21:1242 2 – Upgraded 250 GB SSD to 1T unit as per https://wiki.unraid.net/Replace_A_Cache_Drive 3 – Removed isolcpus=3-5,9-11 stub as it is no longer required with GUI built in pinning TOP command shows that *kworker/6:2+pm* is consuming 83% of the available CPU Logs attached. Thanks ahead of time for looking! tower-diagnostics-20181224-0827.zip Edited December 24, 2018 by landS Quote Link to comment
landS Posted December 29, 2018 Author Share Posted December 29, 2018 (edited) Rebooted server after first post. Happened again within the last 24 hours - 1 thread is stuck at 100% (kworker/6:3+pm). Fresh logs attached. Any help would be appreciated. tower-diagnostics-20181229-0602.zip Edited December 29, 2018 by landS Quote Link to comment
landS Posted January 3, 2019 Author Share Posted January 3, 2019 Hopefully I'm not speaking too soon, but originally passed through a Logitech unified usb receiver to a VM. This usb device has failed and no longer shows up on the list - when attempting the VM start it gave a USB failure message and device id. Inserted a new Logitech unified receiver and it has the same device ID as the original. Since doing this, no more pegged CPU. Quote Link to comment
