kgdb problem

[Sergey Matveychuk]

I've tried to get a back trace from kernel core. But can't:

% kgdb /boot/kernel/kernel /var/crash/vmcore.0
kgdb: kvm_read: invalid address (0x50012)
kgdb: kvm_read: invalid address (0x8256b3c)
kgdb: kvm_read: invalid address (0x4b)
kgdb: kvm_read: invalid address (0x4b)
kgdb: kvm_read: invalid address (0x4b)
kgdb: kvm_read: invalid address (0x4b)
...
(an infinity loop here)

How to fix it?
