Created attachment 307167 [details] Linux build config On an Intel Core Ultra 7 258V running Linux 6.12-rc6, there is periodic stuttering at any time from boot, including in a virtual terminal. These stutters can range from a second or a little longer than a second, but never an unrecoverable freeze. Additionally, when listening to music, these stutters can cause audio to cut out and become choppy. When intel_idle.max_cstate=1 is set, this issue seems to resolve itself. An easy way to replicate this issue is to move a cursor around on a screen, start typing in an application like LibreOffice, and the user will likely encounter a stutter in 5 minutes or less.
