Linus' tree (HEAD=963649d735c8) is spitting out all sorts of garbage
on the serial console - as if the baud rate is being periodically set
to something weird, and then back to 112500. I see over a dozen
blocks of junk interspersed with good output.
This in on ia64 with "console=uart,io,0x3f8" on the command line.
git bisect pointed me here:
