Erm, well, PSE and PGE are already disabled in GENERIC on DP2. Hmm. Can you try doing gdb -k kernel.debug in multiuser under DEBUG and see if gdb behaves any better? Another idea might be to use addr2line instead like so: addr2line -e kernel.debug -f 0xc031f044 -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
