Public bug reported:
Binary package hint: ubiquity
Computer is Lenovo Y530, 64-bit Intel Core2 duo.
I upgraded to Karmic from Jaunty following the official release and my
system has become significantly less stable because of it. In Jaunty
there were absolutely no problems to speak of. Now in Karmic my system
is very unstable: It will randomly freeze while I am using it, whether I
am actively using it or letting it sit. Sometimes it will randomly
reboot, especially on occasions when I close and open the laptop lid
again. Very often it will hang or spontaneously reboot during the boot
or login sequences.
When I say "freeze" or "hang", I mean that the visual display freezes
and the computer becomes absolutely unresponsive to keyboard or mouse
input. When this happens the only solution I have found is to hard
reboot the computer.
My laptop has integrated Intel graphics. I tried downgrading to xserver-
xorg-video-intel-2.4 drivers as I saw recommended in one similar bug
report with no success. If anything the computer became less stable. I
have also tried disabling certain compiz effects and even shut down
compiz entirely with no success, following advice in another ticket.
Another thread I saw suggested uninstalling network-manager and
replacing it with wicd. Same problems. I looked in /etc/log/debug and
/etc/log/kern.log and saw that at the last time when the system hung it
was doing something with wlan0, so I was hoping this would solve my
problem. It didn't.
I'm not sure what information about my system the developers need to
see. I'll post some log excerpts that I saw that I thought looked
interesting, please let me know if I need to post anything else.
Entries in /etc/log/debug when it crashed last night before I went to bed:

Shortly before that, I see this snippet in /etc/log/kern.log that looks scary:
