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

ksymoops 2.3.4 on i586 2.4.0-test9. Options used
