Yes, I also have filed a bug (forgot the number, but it's against the
kernel 2.6.15 and by my name) for crashes.  In my case, I never crash
when using the original 2.6.15-23-[3,6]86 kernel on the original 6.06
installer, but crash with every kernel upgrade since. There are some
others who have added problems to that bug.  Have you tried going back
to that kernel?
