I just want to make sure of which patch > interval we are looking at. It's definitely .24 given the dates for the SYS releases he notes. The diffstat between the two is relatively short [1], but I can't see anything that can be related. This code runs so early, during real mode startup, that my only suspects are: arch/x86/kernel/head_32.S | 2 +- arch/x86/kernel/smpboot_64.c | 2 +- include/asm-generic/tlb.h | 3 - include/asm-x86/byteorder.h | 4 +- include/asm-x86/msr.h | 74 +++++++++-------- [1] http://domsch.com/linux/edd-bug-2008-04-26.patch but none of those are obviously the culprit to me... Werner, the initcall_debug trace would be most helpful; without that I'm not sure how much progress we can make on this.
