    Hi all,

    Just adding my useless complaints the the list -

    Currently running test8-pre1 + rik vm patches, very solid.

    Tonight I tried test9-pre1 -

    The most common occurrence is that vi segfaults on exit.

    Here is a decoded oops immediately after booting test9-pre1:

    jjs
