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. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
