I went back to checkout v3.19 and tried that kernel and all was happiness and joy. So, I started down the bisect path, but after the first iteration I ran into: INSTALL debian/headertmp/usr/include/asm/ (65 files) parsechangelog/debian: warning: debian/changelog(l2): found eof where expected first heading parsechangelog/debian: error: fatal error occurred while parsing debian/changelog dpkg-gencontrol: error: changelog parser /usr/lib/dpkg/parsechangelog/debian gave error exit status 255 scripts/package/Makefile:90: recipe for target 'deb-pkg' failed make[1]: *** [deb-pkg] Error 255 Makefile:1238: recipe for target 'deb-pkg' failed make: *** [deb-pkg] Error 2 Which I'm afraid goes beyond my knowledge of how to deal. Does any of that - either the VxLAN or the build problem - sound familiar? thanks, rick jones
