** Description changed: My system had this disk configuration running 20.04.3 LTS server (fresh install, not upgrade) without issue: 1 SATA SSD ext4 on internal 6Gb SATA port was /dev/sda with 20.04.3 LTS server OS installed. 1 SATA disk ext4 on internal 6Gb SATA port was /dev/sdb 8 SATA disks ext4 on LSI Megaraid 9240-8i in IT mode was /dev/sd[cdefghij] 2 SATA disks (mdraid1) on internal 3Gb SATA ports was /dev/sd[kl] apt upgrade from 5.4.0-7x kernel booting any current linux-image-5.4.0-8x kernel now looks like this: 8 SATA disks ext4 on LSI Megaraid 9240-8i in IT mode are /dev/sd[abcdefgh] 1 SATA SSD ext4 on internal 6Gb SATA port is now /dev/sdi with 20.04.3 OS installed. - 1 SATA disk ext4 on internal 6Gb SATA port now /dev/sdj with 20.04.3 OS installed. + 1 SATA disk ext4 on internal 6Gb SATA port now /dev/sdj 2 SATA disks (mdraid1) on internal 3Gb SATA ports is /dev/sd[kl] The system boots, but any utils e.g. smartd, hdparm etc. referencing /dev/sda are now fubared. Booting any 5.4.0-7x kernel enumerates the disks correctly. Booting any 5.4.0-8x kernel enumerates the disks incorrectly as described above. Booting latest Mainline kernel 5.15.0-051500rc3-generic enumerates the disks correctly.
