Oddly enough, the PIDs for these events_unbound kworker spikes are for kcryptd. Every time going back to a Youtube video in a Firefox tab after some minutes, playing causes the lockup and spike. And again, ONLY on the 6.5 kernels
** Summary changed: - System freezes when playing videos with Kernel 6.5 + System freezes from 100% CPU from kcryptd with Kernel 6.5 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe in Ubuntu. https://bugs.launchpad.net/bugs/2048924 Title: System freezes from 100% CPU from kcryptd with Kernel 6.5 Status in Linux: New Status in linux-hwe package in Ubuntu: New Bug description: Upon updating from the 6.2 kernel series to 6.5.0-14, I have began encountering ~1-3 second freezes when playing videos. This happens in Firefox, VLC and Totem. Booting from any 6.2 kernel resolves the situation, and going back to 6.5 reintroduces the issue every time. My system is running 22.04 and consists of a B450 Chipset, a Ryzen 5600x and a Radeon RX 6600 GPU. I am running Wayland. Disabling OpenGL output and going to X11 xcb in VLC prevents the freeze, and disabling HW acceleration in Firefox does the same. I am wondering therefore if this is an issue with the GPU driver in this kernel.
