I just noticed, that IRQ4 isn't mentioned in /proc/interrupts when I run minicom on the NC6000 in another shell... On the FSC laptop IRQ4 is visible in /proc/interrupts. I tested yesterday Linus's vanilla 2.6.23-rc4 git kernel. Same problem. Maybe related to the second serial port which is a IRDA chip. Syslog from kernel-2.6.22.4-65.fc7 says: Detected unconfigured HP nc6000 family SMSC IrDA chip, pre-configuring device. Setting up Intel 82801 controller and SMSC device found SMC SuperIO Chip (devid=0x5a rev=00 base=0x004e): LPC47N227 smsc_superio_flat(): fir: 0x130, sir: 0x2f8, dma: 03, irq: 5, mode: 0x0e SMsC IrDA Controller found IrCC version 2.0, firport 0x130, sirport 0x2f8 dma=3, irq=5 No transceiver found. Defaulting to Fast pin select IrDA: Registered device irda0 Known problem, patch is still pending for 2.6.23 but may as well go into Fedora now since it's low risk. For the record: adding "pnpacpi=off" on the grub boot command line fixes this temorarily for me (found on google). Chuck, I tried to find the relevant patch in various archives, but couldn't find it. Could you please point me to the patch/thread/discussion ? Patch is here: http://lkml.org/lkml/2007/8/21/291 Also in kernel-2.6.22.5-76.fc7. kernel-2.6.22.5-76.fc7 is in the updates-testing repository with a fix for this bug. hmm... still doesn't seem to work.

dmesg of kernel 2.6.22.9-91.fc7 (added "pnpacpi=off" boot option)
Hello Chuck, above you'll find to dmesgs. Both are from kernel 2.6.22.9-91.fc7. With the second one (where I added "pnpacpi=off") the serial port does work. In the first dmesg log serial port does not work. HTH, Helge Which tty device is the irda port when it's working? ttyS0? Normally the irda port is on ttyS1. when booted with pnpacpi=off, setserial reports: /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 3 modprobe smsc-ircc2 reports in syslog: Detected unconfigured HP nc6000 family SMSC IrDA chip, pre-configuring device. Setting up Intel 82801 controller and SMSC device found SMC SuperIO Chip (devid=0x5a rev=00 base=0x004e): LPC47N227 smsc_superio_flat(): fir: 0x130, sir: 0x2f8, dma: 03, irq: 5, mode: 0x0e SMsC IrDA Controller found IrCC version 2.0, firport 0x130, sirport 0x2f8 dma=3, irq=5 No transceiver found. Defaulting to Fast pin select IrDA: Registered device irda0 ttyS2: LSR safety check engaged! ttyS0: LSR safety check engaged! So, booting with "pnpacpi=off" does make the serial port (ttyS0) working, but IRDA does not. For me serial port is more important than IRDA... Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. something is still buggy. Now I tested mainline 2.6.24-rc7 kernel, and I see: Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled 8250_pci: Unknown symbol serial8250_unregister_port 8250_pci: Unknown symbol serial8250_resume_port 8250_pci: Unknown symbol serial8250_register_port 8250_pci: Unknown symbol serial8250_suspend_port smsc_ircc_present(), addr 0x07d0 - no device found! smsc-ircc2 00:03: disabled ... serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A ... So, serial ttyS0 does now work, but not smsc-ircc (irda). This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping please re-assign to Fedora 9 My serial port quit working when I updated to 9. I see some similar messages here so I'm adding myself to the CC list for this bug. This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'.

Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
