https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245908 Bug ID: 245908 Summary: i915 GPU fails to suspend Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: phk@FreeBSD.org 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).
