"Unfortunately we do not have information to determine 'Product' and 'Component'. The only information we have is that the hanging process is gnome-shell (or at least that this was the case in at least one instance), that the screen blinks and freezes when the problem is observed, and that the hanging CPU served most of the graphics card interrupts. If it is persistent, it _might_ suggest that graphics (presumably the Radeon graphics driver and/or the graphics hardware) is involved. This would be even more likely if the observed PCIe errors point to the graphics card (not sure if the information provided shows the PCIe bus tree; if so I have not found it)." -- Cristian Aravena Romero (caravena) -- 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/1796385 Title: watchdog: BUG: soft lockup - CPU#10 stuck for 22s!
