If so, how can we retrieve a functional crash tool with kernel v5.0 (and following) ? It is known, yes. I'm aware of crash and the gdb scritps should also suffer from this. I'm not sure anyone took a look at it (yet) and I don't think that the `crash' tool will accept the patches unless final printk rework is merged upstream. > Thanks, > Fabre Sebastien Sebastian
