Kernel: 2.6.15-rc5
MPT fusion driver version: 3.03.04
Reproduce: Compile the fusion drivers as module. load driver,
then unload and reload => OOPS => transport_setup_device() =>
attribute_container_add_device.
Something is not being cleaned up properly when the driver is unloaded.
Any ideas?
Here is the oops (running kdb):
