Steps to reproduce:
1.In the UEFI, enable VMD without created RAID disk.
2.Install ubuntu26.04 on M.2 sata disk.
3.use command lsblk to check all NVMEe disk
4.Unplug all NVMe device, then check NVMe device information again via lsblk.
5.plug all NVMe SSD
6.OS reported an error and some of the drives were not recognized.

Compare with Ubuntu 24.04:
There is no errors messages and all NVMe disks can be recognized after re-plug all NVMe SSD
