--- Comment #5 from Frans van der Veer <f.vdv...@chello.nl> --- I can confirm that the the patch proposed by crahman works for me also. My machine holds two INTEL X5650 XEON processors that do not support this avx2 functionality. So the root of this problem is not pyside2, but graphics/qt5-3d. In case it is helpful, here is an exerpt of the system startup log, that shows the processor capabilities: May 25 08:25:12 arwen kernel: FreeBSD 12.2-RELEASE-p6 GENERIC amd64 May 25 08:25:12 arwen kernel: FreeBSD clang version 10.0.1 (g...@github.com:llvm/llvm-project.git llvmorg-10.0.1-0-gef32c611aa2) May 25 08:25:12 arwen kernel: VT(vga): resolution 640x480 May 25 08:25:12 arwen kernel: CPU: Intel(R) Xeon(R) CPU X5650 @ 2.67GHz (2660.06-MHz K8-class CPU) May 25 08:25:12 arwen kernel: Origin="GenuineIntel" Id=0x206c2 Family=0x6 Model=0x2c Stepping=2 May 25 08:25:12 arwen kernel: Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,F XSR,SSE,SSE2,SS,HTT,TM,PBE> May 25 08:25:12 arwen kernel: Features2=0x29ee3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,DCA,SSE4.1,SSE4.2,P OPCNT,AESNI> May 25 08:25:12 arwen kernel: AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> May 25 08:25:12 arwen kernel: AMD Features2=0x1<LAHF> May 25 08:25:12 arwen kernel: VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID May 25 08:25:12 arwen kernel: TSC: P-state invariant, performance statistics May 25 08:25:12 arwen kernel: real memory = 94491377664 (90114 MB) -- You are receiving this mail because: You are the assignee for the bug.
