[olug] Fedora 17, XFCE fails to start Xorg - solved

[Jordan Fox]

I installed XFCE spin last night and had a large number of updates as
well.  Now I'm having problems booting...  The LXDE LiveCD wouldn't
boot and was giving the same errors as I'm getting now with my
install.  I haven't researched it yet.

The errors are
"BUG soft lockup CPU #0" - though I have gotten it for CPU#1 now too.
rcu-sched detected stall
segfault
[sdb] asking for cache data failed  - I only have one hdd though
[sdb] assuming drive cache: write through

I get the last two about [sdb] several times, then usually the boot
continues.  Sometimes everything seems to start fine - sometimes not.
I'll let everyone know what I find... One of the updates was the
kernel and I haven't tried booting from the original kernel yet to see
if that fixes it.
