Hi Joseph, Testing with all previous kernels that I have back to 3.4.0-5-generic result in the following messages (and nothing else):
Loading Linux <version> ... Loading initial ramdisk ... I've tried booting without an initrd, but the behaviour is the same. The recovery boot options for these kernels allow the kernel to boot, but I have still seen the loss of console output with 3.4.0-5-generic even in recovery mode. That said, I have not yet seen the problem with kernels 3.5.0-1-generic -> 3.8.0-14-generic in recovery mode. But it might point to gfx issues. Note that I have only had this problem with a MacBook Air, but I believe apw has seen the same issue with one of his servers so it would be useful to get data from him on this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1103406 Title: kernel disabled console output and keyboard lights in early boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1103406/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
