After a bit more testing.... loading either ide-scsi or ide-cd is sufficient to lock my system dead dead dead if the bios is set to Enhanced mode. After _not_ loading ide-scsi or ide-cd I was able to boot in Enhanced mode. I think I am getting some sortof wierd interrupt storm. Everything freezes for a few second every so often... Here is what I am seeing. $ uptime 00:51:41 up 25 min, 3 users, load average: 0.04, 0.10, 0.07 $ cat /proc/interrupts CPU0 CPU1 0: 152450 0 IO-APIC-edge timer 1: 5334 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 4 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-level acpi 12: 36125 0 IO-APIC-edge PS/2 Mouse 16: 105720 0 IO-APIC-level usb-uhci, usb-uhci, radeon@PCI:1:0:0 17: 0 0 IO-APIC-level Intel ICH5 18: 175250680 2019 IO-APIC-level ide0, ide1, libata, usb-uhci 19: 0 0 IO-APIC-level usb-uhci 22: 90380 0 IO-APIC-level SysKonnect SK-98xx, bttv 23: 0 0 IO-APIC-level ehci_hcd NMI: 0 0 LOC: 156771 156777 ERR: 0 MIS: 2019 I have a P4 with hyperthreading so my kernel is SMP.
