The message is from the isa_nmi() function in sys/i386/isa/nmi.c. What is happening is that yuor machine is raising an NMI (normally used to indicate hardware errors like ECC failures, etc.). Perhaps the card is asserting PERR# or SERR#? I'm not sure if those would trigger an NMI or not though, it might depend on the chipset. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
