But they _are_ useful. Peter certainly noticed very quickly that
there was a problem with the ns83820 driver. Do you think it would
have been better for the kernel to run silently at greatly degraded
performance? I think not.
The optimistic assumption that the network stack is making about
headers being aligned works as long as unaligned headers are
relatively rare. If unaligned headers are common, we'll have to do
something about that for ia64 (and Alpha, SPARC, PA-RISC, MIPS, etc.),
because performance will otherwise suck.
BTW: Peter, I'm not quite sure I understand why your machine got into
real problems because of the printks. The messages are supposed to be
rated limited to at most 5 per 5 second interval. Each message is
about 80 bytes in size, so we're talking about 80 bytes/s. Do you
know what really went wrong here? Did the rate limiting not work as
expected or is there something strange about your setup?
