Having a non-standard kernel is not unheard of. I hit the same problem with acpid. According to the current kernel config /proc/acpi/event is a depreciated interface since 2.6.24 the fact that it is being selected in the official kernels is reflective of the bug. Acpid needs to be fixed.
Note that the debian bug tracker is churning on this same issue. -- acpid upgrade fails on non-standard kernel https://bugs.launchpad.net/bugs/222239 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
