Public bug reported:

After updating Ubuntu, kernel 6.17.0.19-generic fails to boot, dropping to 
"initramfs" with "UUID does not exist / gave up waiting for root filesystem". 
Booting with system 6.17.0-14-generic works normally.
The BIOS storage mode was set to RAID by default.
Booting in AHCI mode also works but causes missing  Wi-fi, Bluetooth an audio.
