BUG Bad page state in process kswapd0 pfn09e23 Error
BUG: Bad page state in process kswapd0 pfn:09e23 is being shown when i try to login using the lish-console
The reason you're seeing this when you launch the Lish console is because Lish shows output from
dmesg, which shows messages from the kernel ring buffer. You can hit the Enter key to get a login prompt if one doesn't appear for you. Once you're logged in, you can run
dmesg -D to disable
dmesg output if you'd like. More information about
dmesg and Lish can be found in this Linode Community Questions site post.
I did some searching on that specific message and it looks like there are a few potential causes. One possible fix would be to change your Linode's kernel if you find that it's a recurring issue or that it's causing your Linode to crash. If you have more information about what your Linode is doing when you see that message, that would be helpful so the Linode Community can take a closer look.
