[Crash-utility] timer command does not work for my ARM target

Dave, There are a few commands that do not work for my ARM vmlinux/vmcore. One of those is "timer". I get the following messages; crash> timer timer: per_cpu_symbol_search(per_cpu__tvec_bases): NULL GETBUF(128 -> 0) GNU_GET_DATATYPE[tvec_root_s]: returned via gdb_error_hook (1 buffer in use) FREEBUF(0) GETBUF(128 -> 0) GNU_GET_DATATYPE[tvec_s]: returned via gdb_error_hook (1 buffer in use) FREEBUF(0) timer: zero-size memory allocation! (called from 81191e6) crash> Both vec_root_size and vec_size are 0 at dump_timer_data_tvec_bases_v1() in kernel.c vec_root_size = (i = ARRAY_LENGTH(tvec_root_s_vec)) ? i : get_array_length("tvec_root_s.vec", NULL, SIZE(list_head)); vec_size = (i = ARRAY_LENGTH(tvec_s_vec)) ? i : get_array_length("tvec_s.vec", NULL, SIZE(list_head)); vec = (ulong *)GETBUF(SIZE(list_head) * MAX(vec_root_size, vec_size)); Do you have any suggestion?
