Running Slackware 12.0 with GRUB as the bootloader. The generic hugesmp.s kernel bundled with the Slackware DVD works magically, however, when I boot the machine with the 2.6.23.12 kernel I compiled myself, IRQ 5 borks and, with it, the SATA controller completely fails to work (no sd* devices in /dev). Other than that, the machine works fine, and the IDE drive works as well.
Here are the seemingly relevant portions of my dmesg:
Code:

Included, for the sake of further insight, is my /proc/interrupts:

Any insight to this would obviously be appreciated. I'm fairly confident it's nothing in my configuration: besides the fact that it looks right to me when I check it out, it seems like the kernel is detecting things properly.
