Loading the radeon module segfaults the kernel, 6.0-current of
yesterday.

I have a Thinkpad with Radeon mobility 7500.  5-stable works on the
same hardware.

ddb trace shows:

bus_generic_activate_resource+0x64
bus_generic_activate_resource+0x64
bus_generic_activate_resource+0x64
pci_alloc_resource+0x226
pci_alloc_resource+0x7x
drm_get_resource_len+0x2f
radeon_preinit+0xa2
drm_attach+0x2d

Not sure what is involved to use gdb at this time.  Can I do serial
gdb with a 6.0-current AMD64 machine running the display? Can I use a
5.x box?

It is 100% reproducable so I can gather more info as needed.

Martin
