I get lockups occasionally on x86 too, but have had higher priority
things to look at. Since regdump is mainly an engineer's tool, we felt
it was a "use at your own risk" feature.
But if we can fix it, all the better.
Tangent -- I would love for somebody to take this output and prettyprint
it in userland ethtool package (d/l and cvs at
http://sf.net/projects/gkernel/).
