I concur with Alan on this point. We are testing 1.3.xx kernels on a
pair of our development machines and are seeing serial overrun errors
that we have never seen before.
The development machines are running our interrogatory engines which
sit and make numerous serial connections to mainframe hosts on the
corporate backbone. The load is not higher on these machines but the
complaints from the kernel are up.
