I can probably test this on the GigE. It is running 2.6.36. Is that recent enough? The 8600 is not cooperating.
The GigE is running 2.6.36 compiled with 4.3.5 built from sources. It seems to run fine. _______________________________________________ > Linuxppc-dev mailing list > Linuxppc-dev@lists.ozlabs.org > https://lists.ozlabs.org/listinfo/linuxppc-dev > _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
