New Kernel update (6.18.xx) wrecks system

[dev-null]

Just a warning for everyone, the new kernel update (6.18.xx I think?) absolutely wrecks the system (atleast it does on Ubuntu Noble). It doesn't boot at all anymore

 

I needed to recover an old kernel from an old backup I had and overwrite the current kernel from rescue mode/petitboot.

 

Kernel 6.12.xx seems to work fine(ish)

 

Just a heads up because I don't know enough to pinpoint the exact cause.

 

 

p.s. for me the kernel means the files in /boot not sure if I used proper terminology

logs?

@Werner Which logs would be usefull? I have a full image from the broken state.

 

Kern.log is empty (0 bytes)

syslog only has log from the last shutdown and ends there

dmesg is from last startup before the system broke

UART logs via serial console

[dev-null]

I don't have a device for that. Which one would you recommend getting? I might try it out later when I get time (not soon so if anyone else is able to post logs?)

FT232R, CH340 or CP2104 are known to work nicely. Search for any usb uart adapter built around one of these.

Don't get  CP2102 because if you ever get a rockchip board it would be useless.
