But when I updated my kernel to 5.4.0-99, the booting Linux system does not ask me for my drive encryption passphrase but instead indicates that it is waiting for a drive partition and eventually times out and drops me into a busybox session. The GRUB arguments are identical for both kernels 5.4.0-94 and 5.4.0-99, yet I can only successfully get into my Linux system using the 5.4.0-94 kernel. I don't know whether the following info is useful or not, since it is gathered only from the kernel 5.4.0-94 where I can actually log in. cat /proc/version_signature : Ubuntu 5.4.0-94.106-generic 5.4.157 lspci-vnvn.log is attached.
