It would be good to first identify which mainline kernel introduce the regression. The 3.2.0-18.28 kernel was based off of upstream 3.2.9. The 3.2.0-19.31 kernel was rebased to 3.2.10, 3.2.11 and 3.2.12.
Could you test the mainline 3.2.11[0] kernel and see if the bug was introduce in that version? If it was not, please test the 3.2.12[1] kernel. There was a build issue with the mainline 3.2.10 kernel, so there is not a prebuilt kernel to test that version. Once we know what version introduced the bug, we can bisect to find the exact commit.
