What to do
AI-suggested
A fix has been implemented in the Linux kernel to check the PTP state in ice_ptp_extts_event() and avoid processing external timestamp events if PTP is disabled. Users should apply the official Linux kernel update that includes this fix to prevent kernel panics related to this issue.
Description
A race condition in the Linux kernel's ice driver can cause a NULL pointer dereference leading to a kernel panic when processing external timestamp events if the Precision Time Protocol (PTP) is disabled. The issue occurs because the ice_ptp_extts_event() function may call ptp_clock_event() with a NULL pointer after the PTP clock has been released. The fix involves checking the PTP state before processing these events to prevent the panic.
