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.
