Just for note: Found this thread with same bug on Mint 18 on Alienware 13 R2: https://forums.linuxmint.com/viewtopic.php?t=234368
Suspend and resume working on Solus LiveCD with kernel 4.8.15. Different (related to ACPI and PCI) startup messages in journal on Solus: kernel: ACPI: Core revision 20160422 kernel: PCI: Using configuration type 1 for base access kernel: ACPI: Enabled 7 GPEs in block 00 to 7F kernel: ACPI : EC: EC stopped kernel: ACPI : EC: GPE = 0x14, I/O: command/status = 0x66, data = 0x62 kernel: ACPI : EC: EC started Different startup messages on journal on Fedora 25 with kernel 4.9.7-201.fc25.x86_64: kernel: ACPI: Core revision 20160831 kernel: acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5 kernel: PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0xe0000000-0xefffffff] (base 0xe0000000) kernel: PCI: MMCONFIG at [mem 0xe0000000-0xefffffff] reserved in E820 kernel: PCI: Using configuration type 1 for base access kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as first EC kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: GPE=0x14, EC_CMD/EC_SC=0x66, EC_DATA=0x62 kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as boot DSDT EC to handle transactions kernel: acpiphp: Slot [1] registered kernel: ACPI: Enabled 7 GPEs in block 00 to 7F kernel: ACPI : EC: event unblocked kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: GPE=0x14, EC_CMD/EC_SC=0x66, EC_DATA=0x62 kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as boot DSDT EC to handle transactions and events So, old kernel has older ACPI revision. Don't know what the rest of the messages mean. But Solus using only pciehp module (PCI Express Hot Plug Controller Driver). New kernel using pciehp module AND acpiphp (ACPI PCI Hot Plug Controller Driver). Something about pci hotplug and something about pci hotplug. And we have bug with pci hotplug. AND NOW THE GREAT NEWS Disabling acpiphp with "acpiphp.disable=1" kernel boot parameter solves our problem. Now I can suspend and I can resume. Don't know what this workaround will break. Also I think this is upstream bug. Can anyone report it? Because I'm too shy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1655100 Title: NVME devices and Network devices disappears upon suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
