Looks like this is a UP vs. SMP module loading issue:. See this thread: http://marc.theaimsgroup.com/?l=linux-ia64&m=112528327800560&w=2
This bug still exists in 2.6.12-6. I'll test a build with Peter's patch.
--- Begin Message ---This patch makes UP and SMP do the same thing as far as module per-cpu data go. Unfortunately it affects core code. To repeat the problem: IA64 keeps per-cpu data in a small data area that is referenced by a 22-bit offset, for both UP and SMP cases. If a module defines per-cpu data, it too will end up in the small-data area. But the module loader at present special-cases the UP treatment of per-cpu data, assumes that it is in the GP-relative data area, and does nothing (for SMP it allocates space, and copies initialised data items into it) The effect is that modules defining per-cpu data fail to load if they're built UP, because of an impossible relocation. The appended patch makes the treatment of per-cpu data uniform between UP and SMP cases. For most architectures, the per-cpu data section will be empty for UP, and so the per-cpu setup code will not be invoked.
