Hello, Tested latest kernel RCs (rc6 and rc7) from kernel.org. Getting multiple identical kernel warnings during boot (both RCs). It is ugly but the system seems fine otherwise. Notebook has Intel GME965/GLE960 mobile graphics. Please notify if further info is needed.

Karsten: Can you check if the problem is still present with kernel 4.4? I found a Debian bug report (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808916) where a user mentioned that upgrading to 4.4 helped.
Hello, I am currently ~100 miles away from the affected system. But I'll return next week. I'll give feedback once i get the chance to test it (~ February 3rd). Best Regards Karsten
Tested with 4.4.1 from kernel.org, the error in drm_atomic.c is gone. But a new one in drm_irq.c showed up. This one is seriously spamming my system logs. ------------[ cut here ]------------ WARNING: CPU: 1 PID: 1003 at drivers/gpu/drm/drm_irq.c:1268 drm_wait_one_vblank+0x13b/0x180 [drm]() vblank wait timed out on crtc 0 Modules linked in: cpufreq_stats cpufreq_userspace pci_stub cpufreq_conservative vboxpci(O) cpufreq_powersave vboxnetadp(O) vboxnetflt(O) vboxdrv(O) nfsd auth_rpcgss oid_registry nfs_acl nfs lockd grace fscache sunrpc joydev hid_generic usbhid hid iTCO_wdt iTCO_vendor_support hp_wmi sparse_keymap arc4 coretemp evdev iwl3945 psmouse serio_raw pcspkr iwlegacy snd_hda_codec_hdmi i915 mac80211 snd_hda_codec_analog snd_hda_codec_generic snd_hda_intel snd_hda_codec snd_hwdep drm_kms_helper lpc_ich mfd_core cfg80211 snd_hda_core snd_pcm rfkill snd_timer drm snd soundcore shpchp i2c_algo_bit i2c_core wmi battery tpm_infineon hp_accel acpi_cpufreq lis3lv02d video tpm_tis input_polldev tpm ac button processor loop fuse parport_pc ppdev lp parport autofs4 usb_storage ext4 crc16 mbcache jbd2 dm_mod sg sd_mod sr_mod cdrom ata_generic ahci libahci ata_piix libata scsi_mod fan thermal ehci_pci uhci_hcd ehci_hcd usbcore usb_common e1000e ptp pps_core CPU: 1 PID: 1003 Comm: Xorg Tainted: G W O 4.4.1+ #5 Hardware name: Hewlett-Packard HP Compaq 6720s/30D8, BIOS 68MDU Ver.
