Re: 2.6.8-rc2 crashes

[Gene Heskett <gene.heskett@verizon.net>]

Greetings;

I just had another crash/lockup, running 2.6.8-rc2-bk3
At the instant, I was looking thru the menu's of the new
kde3.3-beta2, in the window decoration, themes etc menu,
where it got 14% loaded in a 60 megabyte file and it went
away.

--------------
Note restart time, but my script worked, the system 
time is now properly set later in the bootup.  Nice.

Ok, so which direction do I go, bk2, or bk4, for the next test?
