I'm on debian 11, this error doesn't show up every time, but once it appear I need more that one reboot and it will fix automatically without doing nothing, don't know the reason why (just read that can be kernel dependent).
What I want to avoid is that maybe it's just a warning of somethink that will cause a pc break in future (maybe hardware is starting working bad?)
Do you have any sugggestion?
Thanks
I second the advice to switch to a different/previous/known good kernel. That has been the cause a most boot problems for me. I just had it happen on a VM a couple of weeks ago, so I switched to the old kernel, then removed the new kernel. I’ll wait for another kernel before upgrading.
It’s probably worth scanning your disk just in case as well.
ok, I'll backup all data first.
How can I remove old kernel without enter in grub menu (since usually boot works well) and select the oldone as default? Thanks
ok, thank you very much for detailed explanation, yes I remember that I had removed timeout from grub in the past, I will follow your procedure and select previous kernel.
Another question, once I'v selected the older kernel did you think that removing (it's fine using apt?) and resinstall newest kernel will fix the issue or I'v to keep the older kernel?
In case I'v to keep the older kernel how can I avoid that it will be overwritten once I update the os?
