Currently, the ath11k driver does not print a crash signature when a crash happens. Checked by triggering a simulated crash using the command [1] and checking dmesg for logs. [1] echo assert > /sys/kernel/debug/ath11k/../simulate_fw_crash Change the crash logging from debug to informational and add a warning when firmware crash MHI_CB_EE_RDDM happens.
