Status in linux package in Ubuntu: Confirmed Bug description: I rebooted my Ubuntu 20.04.01 LTS OS via SSH and I was unable to reboot. About 7 seconds into the boot process, I get "Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)". I did NOT upgrade any packages before rebooting. This error occurs while attempting to boot with the 5.4.0-70 kernel. I have a RAID0 array on two Samsung 256GB SSDs, and SMART tests correctly with no errors. There is no sign of data loss or corruption on the underlying drives. I have two partitions and RAID arrays, one for /, and one for /boot. I am able to mount my arrays fine, with no issues, in network rescue mode provided by scaleway. I am also able to boot successfully using the 5.4.0-67 kernel, and I used sudo apt install linux-image-generic-hwe-20.04 to get the 5.8 kernel, and that worked fine. My memory is ECC memory.
