[-- Attachment #1 --] I have recently found bug in ltmdm driver. Driver crashes whole system every time when phone call is received while driver is in memory. Problem is in ltmdmsio.c file, trying to read NULL pointer. I fixed this problem, in attachment are two diff files: - patch-sys-dev-ltmdm-ltmdmsio.c - patch file from directory files in ltmdm port directory. I have changed this file to include check not to read memory from NULL pointer - ltmdmsio.c.diff - diff after applying change between original ltmdmsio.c file, and ltmdmsio.c file I have changed Best regards, Ivan P.S. I am using FreeBSD 6.1, problem also existed in FreeBSD 5.x [-- Attachment #2 --] 2089c2089 < if (com->tp != 0 && com->tp->t_hotchar != 0 && recv_data == com->tp->t_hotchar) --- > if (com->tp->t_hotchar != 0 && recv_data == com->tp->t_hotchar)help
