T420 ASL
Also affects Thinkpad X220. Can you try 12.0-STABLE or CURRENT ? I have this with 13.1 on a Thinkpad X201. zzz suspends, on restart screen stays black. kernel: pcib1: failed to set ACPI power state D2 on \_SB_.PCI0: AE_BAD_PARAMETER It still worked with 12.2p7. |
Created attachment 200741 [details] 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.
