Do you have UEFI bios? Can't follow "But since the boot line and the file info is different". What is file info?
My modem is internal, PCI, has 16550A port built-in. It is ttyS4. It doesn't matter what IRQ has my sound card uses, because IRQ sharing between modem ans sound card is in your machine. In mine there is IIRQ 20 sharing between modem and USB. Kernel complains about "nobody cares" are critical messages displayed on every console. So you do not have to do anything, butwatching the screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1087519 Title: Serial port ttyS4 doesn't work in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1087519/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
