I can easily reproduce this any time. It happens when offloading a GL app, here Unigine Heaven 3.0 to the nvidia card. To be more exactly: When starting Unigine the window stays black. To get something useful i have to minimize and maximize the window. Exactly when maximizing the window the trace happens. Hope this helps anyway! ------------[ cut here ]------------ WARNING: CPU: 7 PID: 718 at drivers/gpu/drm/i915/i915_gem.c:3967 i915_gem_free_object+0x124/0x150 [i915]() Modules linked in: af_packet bnep fuse snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_intel snd_hda_codec ath3k btusb bluetooth uvcvideo snd_hwdep videobuf2_core videodev videobuf2_vmalloc videobuf2_memops snd_pcm snd_seq snd_timer arc4 ath9k snd_seq_device mac80211 ath9k_common ath9k_hw ath snd iTCO_wdt sdhci_pci sdhci mmc_core sr_mod sg tg3 ptp pps_core iTCO_vendor_support cfg80211 lpc_ich i2c_i801 pcspkr joydev acer_wmi sparse_keymap rfkill cdrom soundcore snd_page_alloc mperf battery ac autofs4 i915 xhci_hcd processor scsi_dh_alua scsi_dh_hp_sw scsi_dh_emc scsi_dh_rdac scsi_dh nouveau ttm drm_kms_helper drm i2c_algo_bit mxm_wmi video thermal_sys wmi button CPU: 7 PID: 718 Comm: Xorg Not tainted 3.11.0-rc5-desktop+ #27 Hardware name: Acer Aspire V3-571G/VA50_HC_CR, BIOS V1.13 10/09/2012 0000000000000000 0000000000000009 ffffffff81568703 0000000000000000 ffffffff81047f81 ffff88021cf1ab00 ffff88024f1d0000 ffff88025e421930 ffff88021c7bcd40 ffff8802540f2da0 ffffffffa0210a44 ffff88021cf1ab00 Call Trace: [] ? dump_stack+0x50/0x80 [] ? warn_slowpath_common+0x81/0xb0 [] ? i915_gem_free_object+0x124/0x150 [i915] [] ? i915_gem_dmabuf_release+0x80/0x90 [i915] [] ? dma_buf_release+0x23/0x80 [] ? __fput+0xcd/0x230 [] ? task_work_run+0x97/0xd0 [] ? do_notify_resume+0x79/0xa0 [] ? int_signal+0x12/0x17 ---[ end trace 99a0c147e69ddcd1 ]--- Thanks, Tobias Klausmann
