With a patch I believe. Some believe its too dangerous to have a kernel in the middle of an oops trying to write to the disks. And I also belive Linus said it was unnessecary and vendors could patch the kernel if they wanted it. I think I remember seeing it on lwn or just maybe picked it up reading lkm, either way dont expect it in 2.6. -- Scott Henson <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
