The copy_from_user call looks correct to me. > Later, when I inspect 'current->user_stack_xxx' (temporary > added to struct_task) for all processes with 'current->in_suspend' > set, all seems to be zero.

Is it possible that your program has in fact trashed its stack? Another thing to try would be to check the contents of current->user_stack_xxx immediately after you copy it to see whether it is all zero at that point.
