This is a regression caused by commit 665745f274870c921020f610e2c99a3b1613519b Author: Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx> Date: Fri Oct 18 17:47:52 2024 +0300 PCI/bwctrl: Re-add BW notification portdrv as PCIe BW controller which went into v6.13-rc1. It can be overcome by duplicating commit 62e4492c3063048a163d238cd1734273f2fc757d Author: Andreas Noever <andreas.noever@xxxxxxxxx> Date: Mon Jun 9 23:03:32 2014 +0200 PCI: Prevent NULL dereference during pciehp probe in the bandwidth controller driver. I can submit a patch tomorrow unless you or Ilpo beat me to it. (Sorry, I'm still a little sleep deprived today after OSPM Summit.) Thanks, Lukas
