>Release:        5.2.1-RELEASE i386
>Organization:
>Environment:
FreeBSD 5.2.1-RELEASE on an HP Pavilion 3100 (google it) with a Network Everywhere NC100 v2.1 (from what I can tell, a rebranded Linksys LNE100TX).
>Description:
Upon bootup of the installation CD or floppies, while loading drivers (after the boot menu), the dc driver will cause a pagefault. Just before the crash info is:
dc0: <ADMtek AN985 10/100BaseTX> port 0xf800-0xf8ff mem 0xfedffc00-0xfedfffff at device 18.0 on pci0
dc0: couldn't map interrupt
>How-To-Repeat:
Install a Network Everywhere NC100 v2.1 (or possibly any card using dc) in an HP Pavilion 3100. I wouldn't recommend trying it in any other machine, except perhaps one that has a PCI/ISA combo slot (on a riser card). (I'm strongly suspecting that that's the issue.) Then, try to boot FreeBSD.
