Public bug reported: On boot in 13.10 kern.log would state:
Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled 00:0a: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A and my serial modem would work just fine. After upgrading to 14.04 the kernel log contains: Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled serial 00:0a: disabled How do I enable 00:0a? Do I need to recompile the kernel with a different config? ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313981 Title: Kernel disabling serial port ttyS0 on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1313981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
