Subject: [Bug 211003] New: radeon "BUG: unable to handle page fault for address" when hot-unplugging another PCI-e device
Date: Sat, 02 Jan 2021 15:52:09 +0000	[thread overview]
Message-ID: <bug-211003-2300@https.bugzilla.kernel.org/> (raw)

https://bugzilla.kernel.org/show_bug.cgi?id=211003

            Bug ID: 211003
           Summary: radeon "BUG: unable to handle page fault for address"
                    when hot-unplugging another PCI-e device
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.4.80-gentoo-r1-x86_64
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: jernej.jakob@gmail.com
        Regression: No

radeon driver, bug happens when hot-unplugging another PCI-e card that is not
the video card (it was removed via /sys/bus/pci/device/.../remove before
hot-unplugging). It may be a hardware-induced error as this motherboard wasn't
designed for hot-plugging (but it usually works)
