I'm running Fedora 42 on a Thinkpad T420, and I'm getting this same error with kernel 6.16.3-200.fc42.x86_64 and 6.16.4-200.fc42.x86_64. The problem doesn't happen when I use kernel 6.15.10-200.fc42.x86_64. Once it happened after I logged in to Gnome. At other times, it mostly occurred after the system woke up from sleep and tried to reconnect to the wifi network, or sometime after it reconnected to the wifi network. The problem reporting tool, abrt, did detect/catch the issue once. According to it, the problematic package is kernel-core-6.16.4-200.fc42. The Report button is disabled for this System Failure. It does provide a URL - https://retrace.fedoraproject.org/faf/reports/1306123/. # System Details Report --- ## Report details - **Date generated:** 2025-09-05 20:57:41 ## Hardware Information: - **Hardware Model:** Lenovo ThinkPad T420 - **Memory:** 12.0 GiB - **Processor:** Intel® Core™ i5-2520M × 4 - **Graphics:** Intel® HD Graphics 3000 (SNB GT2) - **Disk Capacity:** 500.1 GB ## Software Information: - **Firmware Version:** 83ET82WW (1.52 ) - **OS Name:** Fedora Linux 42 (Workstation Edition) - **OS Build:** (null) - **OS Type:** 64-bit - **GNOME Version:** 48 - **Windowing System:** Wayland - **Kernel Version:** Linux 6.15.10-200.fc42.x86_64 Partial output of the command lspci -kv 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35) Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN Flags: bus master, fast devsel, latency 0, IRQ 27 Memory at f1400000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlwifi Kernel modules: iwlwifi I'm attaching the output of command 'journalctl --no-hostname -b' Created attachment 2105769 [details]
Ouput of command journalctl --no-hostname -b -3
Updated to kernel 6.16.5-200.fc42.x86_64 and the issue is still reproducible. The difference being that a new call trace is present along with the original call trace. Output of command 'journalctl --no-hostname -b' is attached. Created attachment 2106189 [details]
log from kernel version 6.15.10-200.fc42.x86_64
The attachment description above is incorrect. The log is from kernel 6.16.5-200.fc42.x86_64 and not 6.15.10-200.fc42.x86_64. I'm unable to reproduce this issue with kernel 6.16.10. The issue persists up until 6.16.9. With 6.16.10, wifi connects to the network just fine. There is no kernel crash or call trace in the logs. |
