Yes. The recent slews really are bad packets coming in.
I.e., someone (me) did some checksums by hand on raw packets to check.

(Unless there's something really subtle going on in the kernel,
corrupting the raw packet data but passing the PPP CRC).

Do you get it consistently enough to check if using an older kernel
makes it go away?
