kernel log
I have noticed that Dell Dimension 4600 running Ubuntu 12.04 (32-bit) would
become very unstable and hang within minutes after I replaced an AGP Radeon
7000 to a PCI Radeon 9200. It turns out BIOS would not disable the internal
Intel video in the later case. Blacklisting i915 fixed the problem. Nothing
is connected to the Intel video.
I updated to the current mainline kernel (3.15.0-999-generic as of May 7, 2014)
and the problem persisted. To capture the attached logs, I used "init 1" to
bring X11 down. Then I ran "modprobe i915". The kernel oopsed about a minute
later. I was able to save /sys/class/drm/card1/error before it happened.
Attached are the kernel log after "modprobe i915", the output of "lspci
-nvvvxxx", the output of "lsmod" and the error file (compressed).</pre>
