Control: tag -1 moreinfo Hi Rasya,
Thanks for the report! One thing to clarify first: the fatal crash in your log is not actually in the Wi-Fi driver. The iwlwifi/iwldvm "FW Error" messages at 817.795 are non-fatal noise. The panic ~120ms later is a NULL function-pointer call in i915 (the graphics driver): RIP: 0010:0x0 signal_irq_work+0x28a/0x570 [i915] Kernel panic - not syncing: Fatal exception in interrupt So this looks like an i915 crash that may or may not be related to the Wi-Fi activity. Also note the kernel is tainted by out-of-tree modules (thinkpad_ec, tp_smapi, hdaps, acpi_call), which can corrupt unrelated subsystems, so we can't yet treat this as a Debian kernel bug. To move forward, could you please: 1. Reproduce with those out-of-tree DKMS modules unloaded/blacklisted, and confirm with "lsmod" that none are loaded. Does it still panic? 2. Tell us the exact command(s) you run to "restart / reconfigure" the Wi-Fi (e.g. "nmcli radio wifi off/on", "ip link set wlp3s0 down/up", restarting NetworkManager, suspend/resume), and how reliably it reproduces. 3. Retest on the current backports kernel 7.1.13-1~bpo13+1 (you are on 7.1.8). Thanks, Yunseong
