Do you still see the problem? Because if not, then we should look very
specifically for some 32-bit PAE issue.
For example, maybe we use "unsigned long" somewhere where we should
use "phys_addr_t". On x86-64, they obviously end up being the same. On
normal non-PAE x86-32, they are also the same. But ..
Let's wait for what Tejun Heo might say - I've applied his debugging
patch and sent back the results.
Building x86_64 kernel here involves installing a 64bit Linux VM, so I'd
like it to be the last resort.
