Auto reboot issue
Hi All,
Currently in our linode we setup the auto reboot update (debian12) things is its kind of random issue for every instance we got as well as when the auto reboot occurred sometimes its make instance failed to mount sda1 and will go to initramfs state which the solution is just power off and on again it will boot normal again
Are there any suggestions to over come this issue, we've tried added the "scsi_mod.scan=sync" to the Kernel comand line in the /etc/default/grub (and run update-grub ) with out luck
Many thanks

I found a few possible options for you. The easiest solution would be to use the Latest Linode Kernel. Since we've found this is an upstream issue with Grub2 as discussed here, we know that works to resolve the issue.
Next, one user responded in that discussion in this comment and the one right after explaining how to make it so your system uses UUID when booting to identify disks and then how to update your /etc/fstab file to use labels and UUIDs for your disks. I haven't tested this myself, but at least one other user found this helpful.
Finally, since this issue popped up a few years ago, most of our images have been updated to avoid it. So, it's most likely that this will occur if you're using an older distribution or have been doing inline upgrades. If you create new Debian 12 instances and basically follow the Clean Install upgrade process, the server should automatically use UUIDs. It seems like trying to force it to use UUIDs yourself with the previous suggestion would be far easier. I'd just recommend backing up your data in some way and saving all your current configurations in a file in case something goes wrong so you can restore them.
