------- Comment #39 from [EMAIL PROTECTED] 2008-06-18 13:15 -------
Is there any chance to test 32-bit kernel? With this applied to 32-bit
kernel, we should be able to resume without touching stack at all.
(Doing it in 64-bit kernel is not so easy, because we put address on
the stack and ret, instead of jmp...)
