Probably related to: fdc0: <floppy drive controller (FDE)> port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on acpi0 isa_dmainit(2, 40960) failed fd0: <1440-KB 3.5" drive> on fdc0 drive 0 That message is printed by isa_dmainit() in src/sys/amd64/isa/isa_dma.c. You might instrument that function and see where its blowing up. I suspect its getting the buffer from malloc() but the range check below it fails. -- Doug White | FreeBSD: The Power to Serve [EMAIL PROTECTED] | www.FreeBSD.org _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
