Dear Greg,

As you can see, the vm_start address has been clobbered. It seems
this is due to the 3 parameter to remap_pfn_range, where
vma->vm_pgoff get passed, whilst the documentation of remap_pfn_page
suggests this should be a physical address of kernel memory....
Is this indeed a bug or could it be a misconfiguration/definition in
the arch that's wrong?
What kernel version is this?
This is kernel 2.6.30.4-uc0, on ARM, using a heavily modified lpc22xx
architecture. The buffer is allocated with dma_alloc_writecombine(), as
it is a framebuffer.
