Hi The problem is probably in front of the keyboard, but I don't know what I'm doing wrong. A pc of a friend of mine has been crashing lately after installing 6.0R on it. It has ran 4.10R rock solid ever since it was released. Whenever I try to open the dump I get the following: # kgdb -d /usr/crash/ -n 0 /usr/src/sys/i386/compile/SAPPHIRE/kernel.debug kgdb: kvm_read: invalid address (0x50012) kgdb: kvm_read: invalid address (0x7) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) kgdb: kvm_read: invalid address (0x50) <last line repeats until I kill kgdb) Thank for any help you can give. -- greetz Joost joost@jodocus.org
