I checked the attached logs. For config_B (locally built test kernel), the after-replug dmesg does not show the same fatal NVMe failure seen in config_A. In config_B/3-config_B.after_replug.log/dmesg3.log, all three replugged NVMe devices probe and complete queue setup:
10000:01:00.0 -> nvme0, queues ready at line 3611 10000:02:00.0 -> nvme1, queues ready at line 3615 10000:03:00.0 -> nvme2, queues ready at line 3660 So based on the attached dmesg, the locally built test kernel does not reproduce the same NVMe probe/reset/resource-clobbering failure as config_A. If the failure is still seen from userspace, please provide lsblk/nvme list before unplug and after replug, plus any I/O error output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2148638 Title: ubuntu 26.04 - When the NVME hard drives were hot-swapped, the OS reported an error and some of the drives were not recognized.
