Kernel Panic Post-Update

[anon52169069]

I got a kernel panic on my laptop after updating.

Most places say to use a live usb and roll back changes, but I don't have access to another computer to create a live usb; not for the next days.

Is there another solution to this problem? If I knew updating would cause major problems I wouldn't have done so.

Always keep at least 2 kernels to boot from. That might help when one kernel fails.

Where (meaning which OS or computer) are you typing from? [1]
Take a screen shot of the grub-menu or manjaro entry (if applicable) that gives this kernel panic.

[1] where as not like Camden, New Joursey.
Or from a Samsung desktop computer.

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

Boot by editing grub menu.
Revert your kernel update in question and/or install another kernel using mhwd

I have access to a phone or hotel/public computers. The former I have no interface to a usb drive and the latter I would have neither the capability nor permission to run Rufus to create a live usb.

I'm referencing https://wiki.archlinux.org/index.php/General_troubleshooting#Kernel_panics

I tried 'emergency' as parameter- if I did it correctly.


Doesn't change the situation.

If you have any multi-boot system, even non-Manjaro, you may use it to chroot to Manajro.
You can try all grub available options, with or without editing grub commandline to get to TTY (runlevel 1-3).
With no external media, I think that these are all your options, sorry..

@AgentS, OP is using luks and encryption.
I think the kernel panic is due to not 'getting into' the right mapping.
I don't use luks and encryption so I have no idea what the 'mapping' is.
Do you? Also he's trying to boot into 'emergency encrypt device' whatever that is.
Good luck, petsam.

Cheers.

Good luck, petsam.

I don't believe in luck, only in lack of luck..

I don’t use luks and encryption so I have no idea what the ‘mapping’ is.

Neither do I..

I tried reverting all updates done the day the kernel panic occured. Not everything was in the cache, and I still have the problem.
