It looks like you've shared a log excerpt that includes kernel panic messages and traces from a system running a Linux kernel (specifically version 4.4.60). The output suggests that there's a crash related to the ath11k driver, which is often used for Qualcomm Atheros Wi-Fi devices.

It looks like you're dealing with a kernel panic issue related to the ath11k driver on a device running Linux. Here’s a breakdown of the information you've shared, along with some potential steps for troubleshooting:
Key Points from the Log:
Crash Origin:
The kernel panic seems to be triggered by the ath11k_core_ssr_notifier_cb function. This is part of the ath11k driver, which is used for Qualcomm Atheros 11k wireless networking.
BSS Channel Survey Timeout:
The log indicates a timeout in the BSS channel survey (ath11k c000000.wifi: bss channel survey timed out). This might suggest issues with Wi-Fi scanning or initialization.
Stack Trace:
The stack trace shows several calls leading up to the panic, indicating where the fault occurred. Key functions include notifier_call_chain, rproc_stop, and rproc_trigger_recovery.
