Hi,

DragonFly v3.7.1.703.gfeabe-DEVELOPMENT

A panic occurs after loading natapci as module:

>Tue Feb 18 00:04:45 UTC 2014
atapci0: <nVidia nForce MCP61 SATA300 controller> port 0xc880-0xc88f,0xcc00-0xcc03,0xd000-0xd007,0xd080-0xd083,0xd400-0xd407 mem 0xfbdfc000-0xfbdfcfff irq 21 at device 8.0 on pci0

This panic occurred while trying to debug a ATA timeout problem. natapci was built and loaded as module from a customer kernel with no NATA compiled in.

Dump available on: http://leaf.dragonflybsd.org/~tuxillo/archive/crash/natapci_load.txz
