Running FreeBSD-13-STABLE ( FreeBSD 13.2-STABLE #2 stable/13-n255158-9f9b65a0933a: Sat Apr 22 11:20:16 CEST 2023 AMD64) on a Lenovo T560 (see below for some technical specifications). OS has cusatomised kernel. The system is compiled on-site. Scenario one: In /etc/src.conf: PORTS_MODULES+= graphics/drm-kmod PORTS_MODULES+= graphics/drm-510-kmod compiling drm-kmod kernel module whenever a kernel is compiled. In this scenario running X11 with windowmaker (windowmaker-0.95.9_1 x11-wm/windowmaker) as the window system, running wmaker crashes silently the box! This happens with poudriere compiled ports using almost the same FreeBSD 13 as installed on the notebook, it happens also with official ports taken from a freebsd pkg mirror, designated branch "latest". Scenario two: Using the official drm-kmod and drm-510-kmod from the pkg repository designated "latest". The kernel drops this kernel messages onto the console: [...] login: link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type link_elf_obj: symbol __lkpi_fpu_ctx_level undefined linker_load_file: /boot/modules/i915kms.ko - unsupported file type [...] kldstat reveals these modules loaded: $ kldstat Id Refs Address Size Name 1 64 0xffffffff80200000 1afd148 kernel 2 1 0xffffffff81cff000 8050 acpi_wmi.ko 3 1 0xffffffff838f9000 73b0 linprocfs.ko 4 3 0xffffffff83901000 be88 linux_common.ko 5 1 0xffffffff8390d000 3284 linsysfs.ko 6 1 0xffffffff83911000 2eca0 linux64.ko 7 1 0xffffffff83940000 1818b8 i915kms.ko 8 1 0xffffffff83ac2000 73bd8 drm.ko 9 2 0xffffffff83b36000 30fc linuxkpi_gplv2.ko 10 3 0xffffffff83b3a000 62d8 dmabuf.ko 11 1 0xffffffff83b41000 c748 agp.ko 12 1 0xffffffff83b4e000 22e0 uarduno.ko 13 1 0xffffffff83b51000 18310 if_iwm.ko 14 1 0xffffffff83c00000 207d78 iwm8000Cfw.ko 15 1 0xffffffff83b6a000 6730 cuse.ko I tried several window manager, twm seems to work as well as x11-wm/blackbox, but they also crash silently when starting larger applications like libreoffice or firefox. So, the problem is not bound to windowmaker. Another "fun" part is that I also use FreeBSD 13-STABLE on an oldish HP 800 G1 UltraSlim/Small box, also using i915 iGPU driver, also x11-wm/windowmaker, there is no such thing of crashing or even the funny "symbol __lkpi_fpu_ctx_level undefined: message - but the system has an oldish iGPU and is another architecture at least in some details, so the comparison might be inadequate - but as a hint? dmesg of the Lenovo T560: [...] CPU: Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz (2807.99-MHz K8-class CPU) Origin="GenuineIntel" Id=0x406e3 Family=0x6 Model=0x4e Stepping=3 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x7ffafbff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,SDBG,FMA,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND> AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> AMD Features2=0x121<LAHF,ABM,Prefetch> Structured Extended Features=0x29c6fbf<FSGSBASE,TSCADJ,SGX,BMI1,HLE,AVX2,SMEP,BMI2,ERMS,INVPCID,RTM,NFPUSG,MPX,RDSEED,ADX,SMAP,CLFLUSHOPT,PROCTRACE> Structured Extended Features3=0xbc002e00<MCUOPT,MD_CLEAR,TSXFA,IBPB,STIBP,L1DFL,ARCH_CAP,SSBD> XSAVE Features=0xf<XSAVEOPT,XSAVEC,XINUSE,XSAVES> IA32_ARCH_CAPS=0xc04<RSBA> VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics drmn0: <drmn> on vgapci0 vgapci0: child drmn0 requested pci_enable_io vgapci0: child drmn0 requested pci_enable_io [drm] Unable to create a private tmpfs mount, hugepage support will be disabled(-19).
