[   16.914566] ck804xrom ck804xrom_init_one(): Unable to register resource 0x00000000ff000000-0x00000000ffffffff - kernel bug?
[   16.914575] resource map sanity check conflict: 0xff000000

[   16.914640]  [<f87e4246>] ? init_ck804xrom+0x246/0x4c7 [ck804xrom]
[   16.914643]  [<f87e4246>] init_ck804xrom+0x246/0x4c7 [ck804xrom]

the init_ck804xrom driver seems to be requesting a bunch of memory with ioremap that crosses several resources...
which is very bad.

Can you sent the /proc/iomem file ?
