However, it usually results in no CAM debug messages at all. This happens because CAM_LUN_WILDCARD is defined as (~(u_int)0), but the ty= pe of the field where CAM_DEBUG_LUN gets stored is lun_id_t, that is an u_int6= 4_t. If CAM_DEBUG_LUN is not defined, or if it is set to 0xffffffff in the kernel config, then it works as expected, selecting all luns. Changing CAM_LUN_WILDCARD to (~(lun_id_t)0) breaks the build, as some drive= rs use it with 32-bit types, but defining it as (-1) seems to work for me, in = some tests with aacraid on PowerPC64. --=20 You are receiving this mail because: You are the assignee for the bug.=
