What about the swap file? i.e. the Oops is dumped to the first (after the header) sector of the swap file. The computer is restarted automatically. I don't think that it a good idea to continue after an Oops: if you kill a kernel thread, then you have memory corruptions, lost spinlocks, lost semaphores: the computer will crash in a few seconds anyway.
sys_swapoff() clears the first data sector, sys_swapon() checks if the swap partition contains a oops, and if there is an oops it transfers the oops into the system log, and then clears the first sector.
AFAIK, this is would similar to the NT implemenation: if you have no swap file, then the system cannot dump BSOD's.
