Here's a possible workaround (read: quick and dirty hack) for those of us who need to make it work RFN (adjust path to match your kernel/arch):
cd /usr/src/linux-headers-3.5.0-17/arch/x86/include/asm ln -s switch_to.h system.h It worked for me on 3.5.0-17-generic x86_64 (Ubuntu 12.10) Some related discussion at http://www.mindwerks.net/2012/06/wireless- bcm4312-with-the-3-4-and-3-5-kernel/ and https://lkml.org/lkml/2012/3/29/360 Your mileage may vary. I have no idea what other things this workaround might break. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1014834 Title: dahdi-dkms 1:2.5.0.1+dfsg-1ubuntu2: dahdi kernel module failed to build [fatal error: asm/system.h: no such file or directory] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dahdi-linux/+bug/1014834/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
