In order to prove that the issue is not related to sound at all, I tested the same two setups with a PCI network card. I am attaching the results (lspci, lspci -v, and dmesg) below. The NIC is detected in the upper slot, but not in the bottom slot, the same as the sound card.
To reiterate: PCI cards plugged into the bottom slot are not detected by Ubuntu. PCI cards plugged into the slot above the bottom slot are detected. The slot is not bad because the cards work in other operating systems. The issue is NOT specific to a sound card. I will change the title of the bug report. It takes quite a while to shutdown, swap cards, reboot, etc., so I'll wait a little while to see what other logs I should get next time. Now that we know it's slot-related, what logs are important? ** Attachment added: "broken_NIC_results.txt" http://launchpadlibrarian.net/24650309/broken_NIC_results.txt -- Ubuntu does not detect PCI cards on a specific PCI slot https://bugs.launchpad.net/bugs/350140 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
