[Bug 1190120] Re: Kernel Oops - unable to handle kernel NULL pointer dereference; after unbind of a PCI device
** Tags removed: bios-outdated-1.60
** Tags added: latest-bios-1.60
** Tags removed: needs-saucy-test
** Description changed:
I am trying to unbind a PCI device I received a kernel Oops.
I was following instructions described in this KVM document:
http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM
When I get to the unbind step:
-
echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind
I get a kernel Oops. Please note at this point I am not running the kvm
guest, just trying to unbind the PCI device. I do have VT-d enabled in
- the bios and a processor that supports IOMMU.
-
- This problem is repeatable and appears to be isolated to the unbind
- command.
