[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
What you see in grub DEAFAULT command line at boot time is taken from GRUB_CMDLINE_LINUX_DEFAULT What you see at another grub menu item's command line (e.g recovery mode, or another kernel version) is taken from GRUB_CMDLINE_LINUX. What is there more is pure linux meet, it is kernel image name, root directory and initramfs specification. Splash means you want see a picture not text while booting. When booting printk utility prints a lot of messages to console. To avoid this noise most people use quiet kernel option. All the avoided messages may be seen later in /var/log/dmesg. It is up to you what you want to see on console at boot time. It will not however change any system funcionality. Upon BIOS upgrade my modem is dumb again. Many people complain about wrong IRQ care on modern mobos with 3.x.x kernels. It does not relate to modem cards only. However it is specific to PCI bus I think. PCI-E has different IRQ handling than PCI. There is a bus messaging, not PIRQ signalling. I think I will wait for right solution.

[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
I did disable on board sound in the BIOS, no help. File info is the change made in the /etc/default/grub file, whereas the boot line is the edit made on the grub line during boot. The question means - If I alter the /etc/default/grub file and process it with update-grub, it appears to me that the processed grub file seen at boot time is very different (transformed) from /etc/default/grub, so how would I know how to alter the boot time file to allow me to proceed and fix the /etc/default/grub file if I screw it up? It appears that the functionality of our modems is very similar, but still somewhat different. In order to see the nobody cares messages (if they exist), maybe I should remove the quiet splash from GRUB_CMDLINE_LINUX_DEFAULT=quiet splash in the grub file? , or does this just affect some splash screen, not any messages?

[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
Roger, GRUB_CMDLINE_LINUX_DEAFAULT attaches its options to default GRUB menu item only. GRUB_CMDLINE_LINUX does it for each item (recovery modes too). Since you can edit GRUB item line at while boot time, it is up to you which one to choose. But there is no reason to change any of those lines if you did not succeed by editing grub start lines. Re: GRUB_SERIAL_COMMAND the GNU Grub Manual says it is to conf serial line, while booting box via it. Please confirm or not that pci=nocrs is just temporary in the active (by pressing shift, then escape) grub screen, and will disappear on the next boot. Everything you enter to GRUB command WHILE BOOTING your box (i.e. upon pressing e while Grub menu is seen) is TEMPORARY and active for that particular boot only. Therefore you can test new options being added to kernel in a safe way. What you add to GRUB_CMDLINE_LINUX... and issue update-grub afterwards is active for all next system launches. == I experienced my problems upon upgrading to Ubu 12.04 LTS from 8.04 and changing my mobo to AMD990FX-based (Asus Sabertooth). My modem is ZOOM PCI 2920 (not sure about the number). First success came upon adding pci=routeirq option. Then I upgraded BIOS to version 1604 and modem got not accessible again (frankly speaking it was accessible all that time, but its replies went to nowhere due to wrong IRQ assignment). Look at your /var/log/dmesg and grep ttyS there. Focus on IRQ number assigned by kernel. Check in /proc/interrupts if that number is used by bus you have put your modem into, and what device driver cares about that IRQ. You should find 8250 or serial as driver names for your modem if it operates right ( not your case alas!). So if there is IRQ number assigned at boot time ( as checked in dmesg log), and there is not right driver assigned to that IRQ at run time ( as seen in /proc/interrupts) you should focus on investigating events happened in between. If nothing helps you may try kernel option irqpoll. The option will make CPU to care about the interrupts. In general the option will slow machine, but this may not be your case if you are not running several GigaEthernets links. As a valuable experience you may connect the modem to phone line and call the modem through another phone. I wonder if you would see kernel complains about nobody cares on your terminal. -- 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

OK, I understand that items altered in Grub at boot time are temporary.

Both you and me we do have new mobos. Yours is decent Intel piece, mine decent AMD one. One clue more to look for problem source on operating system's side. Dont worry about system boot upon GRUB_CMDLINE_LINUX... change. You can always play with kernel options at boot time and revert changes. 8250.nr_uarts=5 is used by me to limit unnecessary memory occupation by inexsisting ports. Standard 3.x.x kernel reserves room for 32 uarts, often invain. You can limit the number by this option or leave 32 as it is. I see IRQ 17 is shared between modem and sound card. Try to switch off audio in BIOS or pull out of the slot if it is a card. What I found most interesting is that IRQ 17 appears in /proc/interrupts only while using minicom. It should be there or missing all the time, AFAIK Kernel complains about nobody cares IRQ 17 shall be displayed on every console, even prior to any login action. This is a critical system message and as such is broadcasted ( as ordered by syslog.conf ). -- 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
[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
About the sharing of IRQ 17, which is hardware (?), this machine also runs in Windows 7 (completely separate hard drive, not seen in Linux), and the modem works fine there. So would Ubuntu treat this differently than Windows 7? I'll look in a few minutes about if this is in the BIOS, don't think it's a separate card. Also, since this is a confirmed bug, it probably happens on different systems, mobos, sound, etc. ? But since the boot line and the file info is different, how will I know how to undo the file effect at boot edit? Dont worry about system boot upon GRUB_CMDLINE_LINUX... change. You can always play with kernel options at boot time and revert changes. Just to make sure, your modem is internal, with a built-in serial port of it's own? What IRQ is your modem on? What IRQ is your sound on? How do I check on Kernel complains about nobody cares IRQ 17 ? Or is this something that might be hidden by the - GRUB_CMDLINE_LINUX_DEFAULT=quiet splash in the grub file? Maybe I should remove this line value quiet splash? What I found most interesting is that IRQ 17 appears in /proc/interrupts only while using minicom.

[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
OK, I tried both lines. System would not boot with pci=routeirq added. It would boot with pci=nocrs, but again ttyS4 would not work. The way your previous message reads is a bit confusing to me. By (for test if works), do you mean to test if it will boot, or test if the serial port works? If the serial port should have worked, I'm out of luck again. I guess the addition by editing the active grub lines is just to test for that one start if the system will operate with either one of the additions, and to determine which one will work? BTW, the line in the active grub was much different from either GRUB_CMDLINE_LINUX_DEFAULT=quiet splash or - GRUB_CMDLINE_LINUX=, but it did contain both quiet and splash. Please confirm or not that pci=nocrs is just temporary in the active (by pressing shift, then escape) grub screen, and will disappear on the next boot. My best guess now would be to: - add pci=nocrs and the rest of your line to the GRUB_CMDLINE_LINUX=, giving me GRUB_CMDLINE_LINUX=8250.nr_uarts=5 pci=nocrsin /etc/default/grub - run sudo update-grub in Terminal But I have two GRUB_CMDLINE_LINUX lines.

[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
Hi Roger, finally solved similar problem with my server. The solution is to add kernel option PCI=routeirq while booting (for test if works) and if it does to GRUB_CMDLINE_LINUX in /etc/default/grub. Then run update-grub. My GRUB_CMDLINE_LINUX parameter is as follows: GRUB_CMDLINE_LINUX=8250.nr_uarts=5 PCI=routeirq The former kernel option limits ttySx devices to required number. Hope this will help you.

[Bug 1087519] Re: Serial port ttyS4 doesn't work in 12.04
it's normal you need sudo to delete the configuration file in /etc. if the following is literal: cannot write to etc./minicom/minird.xxx, there is an odd problem with the path (etc./). if it's not literal, you probably need to start minicom with sudo to make sure it can write a file in /etc . i still think this is crucial: All I can say is that Minicom flashes Initializing modem at first, and that the Minicom cursor usually disappears when I'm typing the commands.; you should be able to locally echo what you type in the minicom console. you don't know what minicom is using for initialisation (hence the need to try running it without any configuration file; initialisation with the wrong string would mess things up). since it doesn't work in wvdial or cutecom either, i agree the problem is probably related to the serial port. if you have a cd/dvd in this box, you could try the following: reset your modem to defaults in windows; then boot the live dvd/cd installer of ubuntu, don't reinstall but simply use the desktop environment, install minicom in that environment (sudo apt-get install minicom; this will work in the live environment) and try if that works. this would rule out any misconfiguration by your hand. -- 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

The fact that the _devicenode_ exists does not necessarely mean that it is allocated in the kernel. So /dev/ttyS4 may show up with ls but may fail when you try to use it. Check CONFIG_SERIAL_8250_RUNTIME_UARTS in your kernel config file. Most likely place is in /boot. The user who is to use a serial port should be in the 'dialout' group.

For one, check that your kernel support registration of more than 4 ports if you want to use /dev/ttyS4. The standard config is set to 4. In the case that it tells you port is in use, check for a dangling lock file. cu will create a lock in order to prevent double access. 'lsof' may help you to find if an application is accessing the port (too). dmesg may reveal how many serial ports are allocated during boot.

i have a very similar problem: trying to use a serial console (rs232c- cable attached to serial port /dev/ttyS0) with 'cu'. this used to work in older ubuntu-releases. this doesn't work anymore, and it is apparently not related to permissions. on the exact same hardware, this does work with with 'cu' under openbsd and netbsd. full report... http://ubuntuforums.org/showthread.php?t=2089911 related reports... http://ubuntuforums.org/showthread.php?t=2087953 http://ubuntuforums.org/showthread.php?p=12386601 -- 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

This is baffling to me. ALL the serial functions don't work, doesn't matter which app. Can I list the installer for Ubuntu as a package?
