Description of problem: Setup rt in host which has i40e NIC drivers, rt host will crash. Version-Release number of selected component (if applicable): 4.18.0-136.rt24.81.el8.x86_64 How reproducible: 4/4 Steps to Reproduce: 1. Install a rhel8 host. In my testing server, I have 2 XL710 NICs(i40e driver). 2. Install kernel-rt on rhel8 host 3. Reboot host twice, host kernel-rt will crash at the 2nd reboot. Actual results: RT host crash. Expected results: RT host should not crash. Additional info: 1. This might be caused by i40e NIC driver. Testing on another server without i40e NIC driver, the rt host works well. 2. This is a regression bug: kernel-rt-4.18.0-134.rt24.79.el8.x86_64 works well kernel-rt-4.18.0-136.rt24.81.el8.x86_64 crash
It's only kernel-rt issue. 4.18.0-136.el8.x86_64 works well.
Verified with 4.18.0-137.rt24.83.el8.x86_64: RT host works very well after several reboots, no any error any more. So this bug has been fixed very well. Move to 'VERIFIED'.
