--- Begin Message ---Package: libspa-0.2-modules Version: 1.0.1-1 Severity: important Dear Maintainer, Sometimes ...mostly be load growth a lot..., pipe-wire daemon or pipewire-pulse daemon crashes with below message [1]. This happens misalign of loading to YMM register [2][3]. This crash seems to happen at "vlddqu -0x20(%rcx),%ymm2" [2], this need align at 256bit (but, Older Ryzen may be need only align of 128bit). But, RCX register didn't align of 256bits [3]. Value is 0x5650f98e99c4 . So, software related libspa-audioconvert crashes sometime and randomly. I think. Best regards, Ohta.
