Corrupted git repository?

Hi I’m not very familiar with git, but there is something strange with the git repository “git://git.gnumonks.org/openpcd.git”: First of all the the identical revision number “4f7ca20bf40b911c035264d86ef0359d20e7ac88” appears several times: git rev-parse --all 4f7ca20bf40b911c035264d86ef0359d20e7ac88 4f7ca20bf40b911c035264d86ef0359d20e7ac88 4f7ca20bf40b911c035264d86ef0359d20e7ac88 f49cbc1f2503f737a96296993133aec065910935 4f7ca20bf40b911c035264d86ef0359d20e7ac88 3aa065ac48f21ce7c4d0879686fb07b04a60771f 45c13574ff89e3139567943e6a6cae82e754eab0 0febfc567d3f9441811a5490f0ea4d960798d313 Compiling “4f7ca20bf40b911c035264d86ef0359d20e7ac88” results in a not working firmware, even so the changes (PPS changes from Harald) are all correct. (I applied these changes to the v0.4 firmware (revision ebf16b4ddf0dcbadf96aebdec3304f703917fdc7) and it works all nicely.) Could somebody have a look ... Regards, Ben
