Created attachment 282793 [details] firmware with TDLS disabled Hi, the firmware was advertising support for TDLS when it wasn't really supporting it. We disabled the advertisement of the feature in the firmware. Please test. Thank you.
I assume it works.
I have the 8260, on a 4th gen X1, and experienced the same issue. I replaced my firmware with the attached, but am still seeing the same symptoms. slate% sha256sum /usr/lib/firmware/iwlwifi-8265-36.ucode 7929ec4a6eb513f6a9780a49587323926458a3ee03c0c466c8725d376164e4e5 /usr/lib/firmware/iwlwifi-8265-36.ucode 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Subsystem: Intel Corporation Wireless 8260 Kernel driver in use: iwlwifi Kernel modules: iwlwifi [ 10.188846] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [ 10.201399] iwlwifi 0000:04:00.0: loaded firmware version 36.9f0a2d68.0 op_mode iwlmvm [ 10.343925] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 [ 10.421309] iwlwifi 0000:04:00.0: base HW address: 34:f3:9a:60:99:24 [ 10.536301] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0 [ 107.146571] iwlwifi 0000:04:00.0: Microcode SW error detected.

Created attachment 283023 [details] TDLS Setup Request Packet The was the last packet that was captured by tcpdump before the firmware error / hardware reset
Created attachment 283025 [details] dmesg using attached firmware After booting the attached firmware that doesn't advertise TDLS, I still experienced the issue. This is the dmesg output.
Ok, looks like the 8260 uses the iwlwifi-8000C-*.ucode instead of iwlwifi-8265-*.ucode, so that explains why there's no improvement for me.
