dmesg/pciconf/pkg info
On manu's request I tried drm-devel, and that seems to work OK. There's been other reports of syspend/resume not working after base updates, iirc. The graphics drivers hasn't been updated themselves in a little while. In any case, when using drm-current-kmod, did you recompile it locally to match your kernel? Yes, I build a almost-sterile system with src/tools/tools/sysbuild, so kernel/userland/ports is always consistent. Time this ticket out as Overtaken By Events. Well, I have a similar issue with 12.2-STABLE #5 r366177M which I didn't have with r362026. <6>[drm] GPU HANG: ecode 9:1:0xfefffffe, reason: Hang on bcs0, action: drmn0: Resetting bcs0 after gpu hang. Please let me know if there is a right place to report it. |
Not getting out as much these days, I only discovered this last week: Running -current+packages as of april 2nd and as of today (r360240M) suspend does no longer succeed on my T480. The information below is from a freshly built image where all of FreeBSD and all ports are built from scratch. Suspending stalls with the following messages on the console: umass0: detached uhub0: detached [serveral seconds] <6>[drm] GPU HUNG: ecode 9:0:0xcfefcfcf, reason: Hang on rcs0, action: reset drm0: Resetting rcs0 after gpu hang (typed in from unsharp mobile phone picture) In the middle of the screen is an arrow shaped mouse pointer flashing at several tens of Hz. The relevant part of boot-dmesg seems to be: warning: KLD '/boot/kernel/linuxkpi_gplv2.ko' is newer than the linker.hints file 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).
