I've had trouble with GELI on usb harddisks, but that seems to be related to the USB/ATAPI controller.
The message seems to come from /usr/src/sys/geom/eli/g_eli_integrity.c, in the function g_eli_auth_write_done. But for a more detailed analysys, you'd have to set kern.geom.eli.debug to 3, and see what else pops up. The headers indicate that the error number is used according to errno.h, which lists 1 as being "Operation not permitted". Both GELI and GBDE fail with the same length of request. So the error might depend on the underlaying code in the kernel (bio* functions). Are you sure that the disk and controller are working properly?
