I doubt the hardware is making them up. That would suggest power or signalling problems not software. alan, I'd be inclined to agree with you, but with a bit more digging I notice that this is also being reported by other users using Ubuntu with a 2.6.24 kernel. See https://bugs.launchpad.net/ubuntu/+bug/198871 P.S. I'm 99.9% sure that this is not a power supply issue. Signalling - I'm not sure what you mean. There are no drives connected to the JMicron SATA ports. No drives so that implies a sata funny in the AHCI code or Jmicron chip. No immediate ideas on the SATA side so I've reassigned the bug to the sata wizard This problem seems to be resolved since upgrade to kernel-2.6.24.7-92.fc8.x86_64 This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '8'. 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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Description of problem: Spurious events relating to JMicron controller. 03:00.0 SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 03) 03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 03) ata7: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xa frozen ata7: irq_stat 0x00000040, connection status changed ata7: SError: { DevExch } ata7: hard resetting link ata7: SATA link down (SStatus 0 SControl 300) ata7: EH complete ata7 and ata8 are the 2 sata ports on the JMicron controller, but neither have a drive connected. ata9 is the PATA port with a CDROM drive connected. Does not matter if JMicron controller is configured to AHCI or IDE in bios. dmesg shows these events being generated on ata7 at 5-8 second intervals. Version-Release number of selected component (if applicable): kernel-2.6.24.5-85.fc8.x86_64
