I would suggest to reenable power management, and try something else. If you
moved the problematic hubs to bus 5, try to move the problematic webcam to bus
7.

If bus 5 crashes, the problem is only hubs and the webcam is harmless.
If bus 7 crashes, the problem is the webcam.
If neither bus crashes for a few days, it looks like it takes two to the tango.

You could also try a quirk which seems to reduce some bizarre failures on my
AMD B350 chipset. If your kernel has xhci_hcd and xhci_pci built as modules,
run:

rmmod xhci_pci xhci_hcd ; modprobe xhci_hcd quirks=0x4000000 ; modprobe
xhci_pci

If they are built into the kernel image, you need to figure out how to add

xhci_hcd.quirks=0x4000000

to the kernel boot parameters in your distribution's bootloader config.
