I am running Fedora 16 x86_64 and testing vanilla kernel 3.2-rc5. I wanted to test the slabinfo program, so I wrote a small shell script slabinfo-forever.sh (attached) that invokes slabinfo -v every 3 seconds. Just by doing this, I was able to trigger several memory validation warnings, attached in this message. The reason I wanted to test slabinfo is because back when I was running Fedora 14, I had some video issues that seemed consistent with memory corruption. I tried to submit a kernel bug at https://bugzilla.kernel.org/show_bug.cgi?id=42312 just before the kernel.org hack issue, but bugzilla.kernel.org never came up after that.
