Emerging sys-cluster/drbd-kernel with newer kernels will fail. Also, the module has been merged with the mainline linux kernel recently, making this ebuild obsolete for newer kernels. The ebuild however, does not check the kernel version and should return a proper error message when trying to build with a kernel that already includes the drbd module. A list of kernel versions that already include DRBD can be found here: http://www.drbd.org/download/mainline/ Seems like a check for >=2.6.33 would work. Reproducible: Always Steps to Reproduce: 1. Emerge sys-cluster/drbd-kernel on a kernel newer than 2.6.33 2. Observe errors.

Hi John, thanks for reporting this. + 18 Feb 2011; Ultrabug <ultrabug@gentoo.org> drbd-kernel-8.3.8.1.ebuild: + Add kernel >=2.6.33 blocker + I've fixed the ebuild accordingly in main tree, closing bug. Regards
