Some checksum errors should be expected, but not vast numbers of
them. Phones line aren't always terrible clean, and all modems suck
by design, so some data corruption in inevitable.

I would guess earlier kernels didn't report the errors and silently
dropped the offending frames.

If your getting large number of these, it might be a serial overrun
in which case you to be able to reproduce these messages fairly
easily.
