I have reproduced the same issue on the another node:
ASUSTeK P5GD1-VM, Intel 915G chipset, ICH6 IDE controller, IDE dvdrom: SONY DVD-ROM DDU1615 (hda), sata disk: WDC WD1600JS-00M
when I switch IDE controller to the native mode, I see "Disabling IRQ" message, then kernel generates an oops in create_empty_buffers(), like I've reported earlier.
Could somebody please help me to troubleshoot this issue? I've seen this issue on the customer nodes and would like to know how I can work-around this issue without any changes inside motherboard BIOS.
