Make sure that it's taken by explicitly doing that. Without it we got a splat: WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0 ... Workqueue: max3100-0 max3100_work [max3100] RIP: 0010:uart_handle_cts_change+0xa6/0xb0 ... max3100_handlerx+0xc5/0x110 [max3100] max3100_work+0x12a/0x340 [max3100] Solution(s) oracle-linux-upgrade-kernel-uek References https://attackerkb.com/topics/cve-2024-38634 CVE - 2024-38634 ELSA-2024-12581 ELSA-2024-12584 ELSA-2024-12585 ELSA-2024-12611
