Oops with ide-tape?!?!

Hi All! Please forgive me if this has been discussed. I have been reading
as much as possible to see if it has, but haven't found an entry about
this. Decided to catch up with the 2.3 stuff (have been at 2.2.13pre) and
compiled 2.3.18ac5 with ide-tape built-in (non modular) and blam. Oops.
I've included a ksymoops output below. Hope this is helpful. I've
recompiled ide-tape modular, and it loads find, although I haven't had the
chance to use it yet. Been trying to get the ALI15X3 stuff running...

Here's the ksymoops output. Please let me know if I can help to debug
this further.

Thanks!
Bruce
