Ok - looks like I spoke too soon. On shutting down after running all day with no problems (largely unattended) the laptop crashed hard after trying to shutdown.
I found this in syslog after rebooting -- this is Linux 4.0: Apr 2 20:30:07 monster kernel: [ 69.841098] ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150204/nsarguments-95) Apr 2 20:30:07 monster kernel: [ 69.841423] ACPI: \_SB_.PCI0.PEG0.PEGP: failed to evaluate _DSM Apr 2 20:30:07 monster kernel: [ 69.841428] ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150204/nsarguments-95) Apr 2 20:30:22 monster kernel: [ 84.853086] nouveau E[ DRM] failed to idle channel 0xcccc0001 [DRM] Apr 2 20:30:22 monster kernel: [ 84.853284] ------------[ cut here ]------------ Apr 2 20:30:22 monster kernel: [ 84.853290] WARNING: CPU: 4 PID: 206 at /home/kernel/COD/linux/drivers/pci/pci.c:1546 pci_disable_device+0xab/0xc0() Apr 2 20:30:22 monster kernel: [ 84.853292] nouveau 0000:01:00.0: disabling already-disabled device Apr 2 20:30:22 monster kernel: [ 84.853293] Modules linked in: dm_crypt bnep rfcomm binfmt_misc asus_nb_wmi uvcvideo asus_wmi sparse_keymap snd_hda_codec_hdmi videobuf2_vmalloc videobuf2_memops videobuf2_core intel_rapl v4l2_common iosf_mbi snd_hda_codec_realtek x86_pkg_temp_thermal videodev intel_powerclamp snd_hda_codec_generic coretemp btusb media bluetooth kvm_intel snd_hda_intel snd_hda_controller kvm snd_hda_codec snd_hwdep snd_pcm crct10dif_pclmul crc32_pclmul snd_seq_midi snd_seq_midi_event ghash_clmulni_intel snd_rawmidi aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd snd_seq snd_seq_device snd_timer joydev serio_raw snd ie31200_edac mei_me mei shpchp soundcore lpc_ich edac_core mac_hid parport_pc ppdev lp nls_iso8859_1 parport nouveau i915 mxm_wmi ttm i2c_algo_bit drm_kms_helper drm psmouse ahci alx libahci mdio wmi video Apr 2 20:30:22 monster kernel: [ 84.853336] CPU: 4 PID: 206 Comm: kworker/4:1 Not tainted 4.0.0-040000rc6-generic #201503291935 Apr 2 20:30:22 monster kernel: [ 84.853337] Hardware name: ASUSTeK COMPUTER INC.
