after several more similar panics with similar symptoms, I just had one which I seemed to catch before the system totally froze. I was trying to open empathy from the menu which failed, so then I went to open up a terminal to launch it from which also failed. I then ascertained that something was locking up the system so I turned off my wireless and started closing programs: skype, firefox, evolutions, etc. Finally I decided to reboot but was unable to through gnome, and still couldn't open a terminal. I tried ctrl-alt-F1 to get another session to reboot from but that just led to a black screen. I finally started the SysRq combination to reboot, but realized halfway through that I didn't really remember it... so finally I just hard powered off the laptop. When I rebooted, I found multiple bugs over the last hour in the log files, many similar to the bugs I had been experiencing before the kernel panics.
some new (possibly significant lines that I had never seen before were: -A Rhythmbox segfault right before a kernel paging request bug: "Jan 18 13:34:20 austin-laptop kernel: [ 4695.872996] rhythmbox[2643]: segfault at 10 ip 00007f4051cd948c sp 00007fffbdf79210 error 6 in libc-2.10.1.so[7f4051c61000+166000] Jan 18 13:34:20 austin-laptop wpa_supplicant[1173]: CTRL-EVENT-SCAN-RESULTS Jan 18 13:34:39 austin-laptop kernel: [ 4715.051925] BUG: unable to handle kernel paging request at 000000000032e4af" -Right before I finally gave up and forced a reboot there is this line: "Jan 18 16:18:01 austin-laptop kernel: [14517.632516] Fixing recursive fault but reboot is needed!"
