I don't draw that same conclusion as you. I feel you have two separate issues that can cause severe problems.
If accessing the DPCD sysfs file provided by nouveau crashes in a way that is enough to taint it there is certainly a nouveau bug (the original one you filed here). For this particular bug; the most important thing to triage it would be to try a newer kernel and see if it's been fixed. If it's been fixed in a newer kernel then it's a backport effort for the kernel team to bring that fix back to Ubuntu's kernel. If it remains an issue in the latest upstream kernel you should report it to the appropriate upstream bug tracker: https://gitlab.freedesktop.org/drm/nouveau -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2098668 Title: nouveau crashes when fwupd requests DPCD reads on drm_dp_auxN Status in fwupd package in Ubuntu: Invalid Status in linux package in Ubuntu: New Bug description: I was reviewing logs while trying to find evidence of an unrelated issue (which turned out to be related, it is a nouveau driver crashing on DPCD requests, see the comments below) and found that fwupd.service fails to start due to a timeout.
