sys-fs/udev-220-r3 has multiple issues: 1) device sysfs attrs aren't loaded Example output: # udevadm info --attribute-walk --path=/sys/class/net/eth1 Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/devices/pci0000:00/0000:00:13.0/net/eth1': KERNEL=="eth1" SUBSYSTEM=="net" DRIVER=="" looking at parent device '/devices/pci0000:00/0000:00:13.0': KERNELS=="0000:00:13.0" SUBSYSTEMS=="pci" DRIVERS=="8139too" looking at parent device '/devices/pci0000:00': KERNELS=="pci0000:00" SUBSYSTEMS=="" DRIVERS=="" Notice no ATTR{foo}=="bar" lines. This breaks all attribute matching.

After applying these upstream fixes in order of their commit dates sys-fs/udev-220-r3 seems to work OK. Reproducible: Always
We should also look into back-porting these for systemd if necessary.
Do these issues exist with udev-222?
This is fixed in udev-222.
