The third one suggested by Linus is the most useful and most direct one IMO. Such a 'oops mode' screen would be useful for regular kernel crashes as well. Also, have you tried BIOS warm reset vector, which is supposed to reboot without clearing RAM contents - how well does it work in practice on typical laptops? If on crash we could reboot without memory getting cleared that would open up a vast area of space to store the kernel log into (RAM). Thanks, Ingo
