I haven't seen this but then I haven't tried to run a kernel in SKI for
months.

This I know about. The ia32 support in SKI is pretty broken right now.

I have a SKI command file which carefully runs the bootloader up to the
first instruction of the kernel and then breaks. You can find it in
src/sys/ia64/skiload/skiload.cmd. You should be using skiload to load
the kernel rather than the ancient linux-derived bootloader I started
with. This might be the cause of your msgaddchar problems, I guess.

With skiload, use boot -v as usual.
