In the Linux kernel, the following vulnerability has been resolved: ARM: dts: bcm2711: Fix xHCI power-domain During s2idle tests on the Raspberry CM4 the VPU firmware always crashes on xHCI power-domain resume: root@raspberrypi:/sys/power# echo freeze > state [ 70.724347] xhci_suspend finished [ 70.727730] xhci_plat_suspend finished [ 70.755624] bcm2835-power bcm2835-power: Power grafx off [ 70.761127] USB: Set power to 0 [ 74.653040] USB: Failed to set power to 1 (-110) This seems to be caused because of the mixed usage of raspberrypi-power and bcm2835-power at the same time. So avoid the usage of the VPU firmware power-domain driver, which prevents the VPU crash.
