I wish I had a machine to test on so I wouldn't have to bother you about it. Any chance you could point me at the complete before/after dmesg logs? There should be information about the PCI host bridge apertures and offsets in the "after" log. If that's not enough, we might need to collect new before/after logs with something like this (whitespace-mangled): --- a/arch/powerpc/Makefile +++ b/arch/powerpc/Makefile @@ -71,7 +71,7 @@ CFLAGS-$(CONFIG_PPC64) := -mminimal-toc -mtraceback=no -mcall-aixdesc CFLAGS-$(CONFIG_PPC32) := -ffixed-r2 -mmultiple KBUILD_CPPFLAGS += -Iarch/$(ARCH) KBUILD_AFLAGS += -Iarch/$(ARCH) -KBUILD_CFLAGS += -msoft-float -pipe -Iarch/$(ARCH) $(CFLAGS-y) +KBUILD_CFLAGS += -msoft-float -pipe -Iarch/$(ARCH) $(CFLAGS-y) -DDEBUG CPP = $(CC) -E $(KBUILD_CFLAGS) CHECKFLAGS += -m$(CONFIG_WORD_SIZE) -D__powerpc__ -D__powerpc$(CONFIG_WORD_SIZE)__ > Freeing unused kernel memory: 488k freed > modprobe used greatest stack depth: 10624 bytes left > dracut: dracut-004-32.el6 > udev: starting version 147 > udevd (1161): /proc/1161/oom_adj is deprecated, please use /proc/1161/oom_score_adj instead. > setfont used greatest stack depth: 10528 bytes left > dracut: Starting plymouth daemon > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2689 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 9 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2701 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 20 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2713 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2725 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2737 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2749 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2761 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 7 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2773 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 7 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2785 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2797 > initcall .wait_scan_init+0x0/0xc4 [scsi_wait_scan] returned 0 after 8 usecs > calling .wait_scan_init+0x0/0xc4 [scsi_wait_scan] @ 2809 > > and eventually our test system decides the machine is dead.
