https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234595 Bug ID: 234595 Summary: Suspend/resume issues with PCI bus on ThinkPad T420 Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: kevinz5000@gmail.com Created attachment 200741 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D200741&action= =3Dedit dmesg output Issuing: # zzz On a ThinkPad T420, either with CSM or UEFI boot, gives: pci0: failed to set ACPI power state D3 on \134_SB_.PCI0.VID_: AE_BAD_PARAM= ETER pcib0: failed to set ACPI power state D2 on \134_SB_.PCI0: AE_BAD_PARAMETER acpi0: cleared fixed power button status Then, either after the screen goes blank, or on resume, some things on the = PCI bus end up broken. For me, it's the ehci controller and ethernet (em) controller. ehci_interrupt: unrecoverable error, controller halted cmd=3D0xffffffff ... sts=3D0xffffffff ... ien=3D0xffffffff frindex=3D0xffffffff ctrdsegm=3D0xffffffff periodic=3D0xffffffff async=3D0x= ffffffff port 1 status=3D0xffffffff port 2 status=3D0xffffffff port 3 status=3D0xffffffff ... ehci_interrupt: blocking interrupts 0x10 em does not give any dmesg output, continues to show up in ifconfig, but do= es not seem to work. Suspend/resume worked on this machine in 11.2-RELEASE. I suspect something broke with the ACPI upgrade, but will keep investigating. --=20 You are receiving this mail because: You are the assignee for the bug.=
