I'm sure someone understands this better than I, but I'll take a stab at it.

"udevd" == message from the udev daemon.  Udev is the device system that
"connects" your hardware devices to the kernel by created the /dev/*
file tree and loading the appropriate driver.

Udev figures this stuff all out buy files of rules in
/etc/udev/...somewhere (varies slightly by distribution).  The rules
files have a line for each possible device and driver.  Each rule line
will define certain attributes of the device, like vendor ID or device
model, to match it to the correct driver.

I take the messages you are seeing to indicate the rules files have an
attribute "ATTRS" listed in them that udevd does not understand,
Perhaps you recently updated udevd and the new version doesn't
understand this now old attribute or the rules files were updated
creating the opposite problem.  (Just guessing here.)

While it may create large log file, if all your hardware is working as
expected, I don't think it is anything to get too concerned about.
