I'm running Linux Mint 21.1 Xfce and it was all good up to and including 5.15.0-60-generic but after updating to -67 I started getting an "out of memory" error at boot (hit any key) followed by "kernel panic, not syncing, VFS unable to mount rootfs on unknown block".
Booting trusty old version -60 via advanced options worked fine so I figured I'd just skip -67 and wait until the next version. But now -69 is out and doing the same thing. So a bit of Googling turned up these:
So I tried this:
sudo mount /dev/nvme0n1p1 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
update-initramfs -u -k 5.15.0-69-generic
But only ended up losing my Windows Grub entry and -69 STILL won't boot. It's fairly new hardware (13700K, DDR5, 4070 Ti) so I wondered if that has anything to do with it, but it works fine on -60 and earlier? I'm happy enough to stick with an older kernel for now, but eventually that's going to become a undesirable security-wise if I'm way out-of-date.
Any help would be appreciated.
