Subject: Linux warns `rtsx_pci 0000:3b:00.0: PM: dpm_run_callback():
 pci_pm_resume returns -110`

#regzbot introduced: b46c89c08f41..aa22f4da2a46

Dear Linux folks,


On the Intel Kaby Lake laptop Dell XPS 13 9360, at least Linux 
6.13.0-07632-gaa22f4da2a46 logs the new warnings:

     rtsx_pci 0000:3b:00.0: Unable to change power state from D0 to 
D3hot, device inaccessible
     rtsx_pci 0000:3b:00.0: PM: dpm_run_callback(): pci_pm_resume 
returns -110
     rtsx_pci 0000:3b:00.0: PM: failed to resume async: error -110

These were not present up to including Linux 6.13.0-07078-gb46c89c08f41.

It looks like the first warning is not always logged:

     $ sudo dmesg | grep rtsx
     [    8.612537] rtsx_pci 0000:3b:00.0: enabling device (0000 -> 0002)
     [ 2010.081170] rtsx_pci 0000:3b:00.0: Unable to change power state 
from D0 to D3hot, device inaccessible
     [ 2010.236503] rtsx_pci 0000:3b:00.0: PM: dpm_run_callback(): 
pci_pm_resume returns -110
     [ 2010.236525] rtsx_pci 0000:3b:00.0: PM: failed to resume async: 
error -110
     [ 4115.541202] rtsx_pci 0000:3b:00.0: PM: dpm_run_callback(): 
pci_pm_resume returns -110
     [ 4115.541216] rtsx_pci 0000:3b:00.0: PM: failed to resume async: 
error -110

Logs from Linux 6.14-rc1 are attached. Bisection is only possible after 
next Sunday.


Kind regards,

Paul
