Oh yuck. The sym driver has its own memory allocator that caps allocations
at 1 page. Since PAGE_SIZE on amd64 is 4k, and the 64 bit resizing of the
structs puts the size over 4k, the struct will need some pruning.
(PAGE_SIZE is 8k on sparc64 (and alpha?) which is why this hasn't been
caught previously.)

You will have to use a different controller until the driver can be fixed.
