The issue has been resolved (see bugzilla), though not yet upstreamed. Thanks

This happens roughly once every three sessions, with no obvious trigger, thus no way to reproduce but to boot and wait, usually a couple of hours. The error displayed on dmesg is the following: ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.MMRD] (Node ffff8802468b4f50), AE_AML_INFINITE_LOOP (20150930/psparse-542) ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.RDMB] (Node ffff8802468b5938), AE_AML_INFINITE_LOOP (20150930/psparse-542) ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.RDMW] (Node ffff8802468b5960), AE_AML_INFINITE_LOOP (20150930/psparse-542) ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.BAT0._BST] (Node ffff8802468b54d8), AE_AML_INFINITE_LOOP (20150930/psparse-542) This makes every process that depends on reading battery state hang indefinitely, including suspend and shutdown. It is my understanding that \_SB.PCI0.LPCB.EC0.MMRD is the PCI Node of Memory Read 32-bit double word, and that these other nodes reference it in their definitions. In the session I share (dmesg), no event gets registered in dmesg for several minutes before these errors. As I said, no obvious trigger. Also, perhaps related, I find two other ACPI parsing/execution errors that repeat on every boot and frequently show on dmesg without any visible effect: ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.ACCR] (Node ffff8802b68b4ed8), AE_AML_INFINITE_LOOP (20150930/psparse-542) ACPI Error: Method parse/execution failed [\_SB.PCI0.ACEL._STA] (Node ffff8802b68b90a0), AE_AML_INFINITE_LOOP (20150930/psparse-542) I haven't been able to find anything on the first node. This has been reproducible on kernel 3.19. Maybe worth mentioning. When disassembling DSDT from IASL I get a warning: iASL Warning: There were 6 external control methods found during disassembly, but additional ACPI tables to resolve these externals were not specified. The resulting disassembler output file may not compile because the disassembler did not know how many arguments to assign to these methods. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC1D0p: m 3446 F...m pulseaudio /dev/snd/controlC1: m 3446 F.... pulseaudio /dev/snd/controlC0: m 3446 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=bed51ac4-b6b1-43fc-8304-7b7b4a88b7bb InstallationDate: Installed on 2016-08-06 (26 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: Hewlett-Packard HP ENVY m4 Notebook PC Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-34-generic root=UUID=5a61dc86-7c12-4f8c-9f3c-717f399c2afc ro quiet splash acpi_backlight=vendor acpi_osi=Linux "acpi_osi=!Windows 2012" vt.handoff=7 ProcVersionSignature: Ubuntu 4.4.0-34.53-generic 4.4.15 RelatedPackageVersions: linux-restricted-modules-4.4.0-34-generic N/A linux-backports-modules-4.4.0-34-generic N/A linux-firmware 1.157.3 Tags: xenial Uname: Linux 4.4.0-34-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 06/04/2014 dmi.bios.vendor: Insyde dmi.bios.version: F.18 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 18EE dmi.board.vendor: Hewlett-Packard dmi.board.version: 78.0D dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.18:bd06/04/2014:svnHewlett-Packard:pnHPENVYm4NotebookPC:pvr0877100022345B10001620130:rvnHewlett-Packard:rn18EE:rvr78.0D:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP ENVY m4 Notebook PC dmi.product.version: 0877100022345B10001620130 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1615200/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
