Using acpi_osi=! acpi_osi="Windows 2009", I can launch lspci, but the system freezes a minute or so later with [ 92.249957] nouveau 0000:01:00.0: DRM: resuming kernel object tree...

Is there any debug info I can provide ? @Pablo I have tried pcie_port_pm=off alone or together with the acpi_osi boot flags, but it doesn't seem to make any difference.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
