Hi, I am working on getting FreeBSD to boot on a new ARM based board, and am hitting this issue any time I load a driver for the PCI based devices on the board. My current code can be found here: http://www.tomjudge.com/tmp/em7210.patch Here is the back trace of the problem (which i can repeat with em and ohci drivers): RedBoot> load -b 0x01008000 kernel Using default protocol (TFTP) Address offset = 0x40000000 Entry point: 0x01008100, address range: 0x01008000-0x01349e28 RedBoot> go KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2009 The FreeBSD Project.
