Hi, ...

I am just wondering if i got dropped from the CCs or if there was no further
discussion on this.

The 2.6.19 kernel doesn't build when the efika patches are applied and the
ohci modules are built. We need a solution for this. Even disabling the patch
for ohci fails to build the ohci driver, but this could be a bad manipulation.

Is there any hint on the right way to go for this ?
