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: b...@freebsd.org
Reporter: kevinz5...@gmail.com

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_PARAMETER
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=0xffffffff
...
sts=0xffffffff
...
ien=0xffffffff
frindex=0xffffffff ctrdsegm=0xffffffff periodic=0xffffffff async=0xffffffff
port 1 status=0xffffffff
port 2 status=0xffffffff
port 3 status=0xffffffff
...
ehci_interrupt: blocking interrupts 0x10
em does not give any dmesg output, continues to show up in ifconfig, but does
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.
