It looks like the key issue here is the failure to load the efi_pstore and drm kernel modules in the newer kernel version. Here's a step-by-step approach to troubleshoot and hopefully resolve the issue:
Safe Mode Boot:
Boot into a safe mode or recovery mode to access a terminal. This will allow you to work on the system without the problematic kernel.
Check Kernel Modules:
Ensure that the modules are present for the newer kernel. Navigate to the appropriate directory:
cd /lib/modules/6.2.0.26/kernel/drivers/
And then find the modules:
find . -name "efi_pstore.ko"
find . -name "drm.ko"
Manually Load Modules:
Try to manually load the modules to see if there's an error:
modprobe efi_pstore
modprobe drm
Review Kernel Logs:
Review the kernel logs for any errors related to these modules:
dmesg | grep -i "efi_pstore\|drm"
Sometimes, specific kernel boot parameters can cause issues. Review your bootloader's configuration (likely GRUB) to see if there are any unusual parameters set for the new kernel.
Graphics Drivers:
Although you mentioned you are not using Nvidia drivers, the kernel could still be having issues with your RTX 3070. You might consider booting with the nomodeset parameter to bypass any GPU issues during boot. If that works, then it's a clue that the issue is graphics related.
Reinstall Kernel:
It's possible that there was a problem during the kernel upgrade. Consider reinstalling the 6.2.0.26 kernel...
