So I recently installed eOS with LVM checked at boot to use the whole disk. I've never had an issue on previous devices, but this one seems to be a bit less than happy.
systemd-analyze immediately makes it clear that this is not a userspace issue, as that is all handled incredibly quickly:
Startup finished in 35.868s (kernel) + 5.333s (userspace) = 41.201s graphical.target reached after 2.118s in userspace
dmesg I find a rather suspect output:
[ 4.633861] Btrfs loaded, crc32c=crc32c-intel [ 35.740814] EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts: (null)
Seems to me that there is some issue with mounting the root partition, although my knowledge stops short of being able to diagnose why this is happening, or resolving the issue in any way. I have heard that LVM can occasionally cause issues on some SSDs, which I suspect may well be the issue here, but I would rather avoid having to drop LVM if at all possible.
Any ideas where I might start looking?
