Subject: 2.6.22-rc6 bad page error

This happened on an Alpha computer (433au) running 2.6.22-rc6.  The
error was triggered when I started up a NX KDE session, which I've
done successfully on all occasions prior to this one.  In other words,
I wasn't doing anything out of the ordinary...  The machine is still up
and running as I type this, and can't/won't be rebooted for a few hours
if there's any other troubleshooting information I need to retrieve that
might be helpful.
