Now suppose this.
The kernel has to save the video memory contents somewhereto restore it after
pressing Enter. This may swap something out. Whoops, swap is on that failed disk.
Or: lock the memory in advance, to avoid the use of swap. But this is not better
than doing the same thing from a userspace application that shows a pop-up
ballon with the contents of this oops. And it won't be affected by a disk
failure, because it has everything already in memory.
If you have enough video memory, you may use that to save the contents
of the screen.
If you dont, then save it in main memory. if you dont have space
there, then i guess not saving the contents is acceptable.
