Hi, Zixing Liu With the mainline kernel 6.16.rc2, we are unable to test due to other issues.
We are experiencing continuous drive reconnects just after running the test. We are planning to revert to the 6.8.x kernel. Please let me know if we can provide any additional logs to help debug these issues. As of today, this problem is blocking our deployment. -- 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/2112304 Title: All Drives disconnected for both the paths when maim (Medusa IO) is blocked continuously followed by automatic network config reset Status in linux package in Ubuntu: New Bug description: Steps: Connect the hosts to the NVMeOF enclosure and run the IOs on the drives.
