Recently I experienced random system lockups at almost every login, and I finally found the issue - the UEFI partition was full, so I was probably not booting the right kernel because the boot loader wasn't updated.
I have tried to find more information on the questions below, but have been unable to find out:
- How many kernel images are preserved in the UEFI partition?
- How can I remove old images UEFI partition to prevent it for going full?
- How can I rollback to another kernel? (I see this feature being mentioned a lot, but I cannot find any description of how it's done)
- it retains the latest installed kernel, plus the current running kernel on updates
- there was a bug preventing the old kernels/initrds from being cleaned up (had been fixed). So you may have to mount the ESP and remove the existing older kernels, but not in future
- if you're on UEFI, you can spam space during boot to get the menu to show. On grub, the will be alternative boot options which has the older kernel (assuming you're using the Solus grub)
