Description of problem: When this module (peaq_wmi) is loaded, it sends a continuous stream of nul characters to the console (displayed as ^@), every second or so. Version-Release number of selected component (if applicable): kernel-4.13.4-200.fc26.x86_64 How reproducible: Always. Steps to Reproduce: 1. Let the module get loaded by kernel on relevant hardware. Actual results: Nul bombed console. Expected results: Quiet console. Additional info: Blacklisting the module avoids the problem.
I think this driver is new for 4.13. Hans, any idea what might be going on here?
Hi, (In reply to Laura Abbott from comment #1) > I think this driver is new for 4.13. Hans, any idea what might be going on > here? I've received a similar bug report by email, it seems that the WMI UUID the driver is binding to is used on (some) other devices to and the WMI interface behaves differently there. Bojan, what hardware are you seeing this on ? Also I'm going to need some info from your machine to debug this, can you run: sudo dnf install acpica-tools sudo acpidump -o machinename.acpidump And then attach the generated machinename.acpidump file here, as well as run: sudo dnf install dmidecode sudo dmidecode > machinename.dmi And then attach the generated machinename.dmi file here? Thanks & Regards, Hans

Created attachment 1334860 [details] [PATCH] platform/x86: peaq-wmi: Add DMI check before binding to the WMI interface Thank you for the info. I'm attaching a patch which fixes this. I'm also submitting this patch to the upstream kernel (with a Cc: stable). Laura can you add this patch to the Fedora kernels to fix this for now ?
