https://bugzilla.kernel.org/show_bug.cgi?id=206365 Bug ID: 206365 Summary: kernel NULL pointer dereference when charger is unplugged Product: Drivers Version: 2.5 Kernel Version: 5.3.4-300.fc31.x86_64 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: andrea.lagala@xxxxxxxxx Regression: No Created attachment 287039 --> https://bugzilla.kernel.org/attachment.cgi?id=287039&action=edit lshw output Every time I unplug my charger, I get a oops about a NULL pointer dereference. The computer then slows down to a crawl, up until it fully freezes. ABRT tries to get a report, but never gets to write any data. I installed kdump and forced the panic on oops setting to get as much data as possible. I initially thought that tlp was the culprit; deactivating it yielded no improvements. Then, reading dmesg while troubleshooting I noticed lockdown was blocking direct writes to registers. I disabled Secure Boot but the problem still is there. -- You are receiving this mail because: You are watching the assignee of the bug.
