https://bugzilla.kernel.org/show_bug.cgi?id=211895 --- Comment #2 from Petr Špaček (pspacek@xxxxxxx) --- Panic reproduced also on Dell Latitude E5470/0MT53G, BIOS 1.23.3 08/04/2020 with kernel 5.11.1. First log lines about WMI are: wmi_bus wmi_bus-PNP0C14:01: WQBC data block query control method not found acpi PNP0C14:02: duplicate WMI GUID 05901221-D566-11D1-B2F0-00A0C9062910 (first instance was on PNP0C14:01) acpi PNP0C14:03: duplicate WMI GUID 05901221-D566-11D1-B2F0-00A0C9062910 (first instance was on PNP0C14:01) and then boot goes on for a second. Several processes cause stack traces to be printed, pointing all over the place. Blacklisting the module workarounds the problem. -- You may reply to this email to add a comment.
