2 * Text: "Allocating AES fallback algorithm %s failed\n"
7 * The advanced encryption standard (AES) algorithm includes three modes with
8 * 128-bit, 192-bit, and 256-bit keys. Your hardware system only provides
9 * hardware acceleration for the 128-bit mode. The aes_s390 module failed to
10 * allocate a software fallback for the AES modes that are not supported by the
11 * hardware. A possible reason for this problem is that the aes_generic module
12 * that provides the fallback algorithms is not available.
14 * Use the 128-bit mode only or ensure that the aes_generic module is available
15 * and loaded and reload the aes_s390 module.

22 * The advanced encryption standard (AES) algorithm includes three modes with
23 * 128-bit, 192-bit, and 256-bit keys. Your hardware system only provides
24 * hardware acceleration for the 128-bit key mode. The aes_s390 module
25 * will use the less performant software fallback algorithm for the 192-bit
26 * and 256-bit key modes.
