Description of problem: After upgrading to any 2.6.22 kernel (latest tried is 2.6.22.1-41), the system fails to load right after trying to start Nash. It is unable to find any Volume Group, hence no root partition. This is happening on an Asus A8V-XE mainboard with dual core AMD 64 processor, with SATA hard drives (I have already tried swapping the SATA cables, and also removing the extra 'data' drive). System continue to work on 2.6.21 kernel. Version-Release number of selected component (if applicable): 2.6.22.1-41 How reproducible: Always Steps to Reproduce: 1. Upgrade kernel to 2.6.22.x version 2. Restart system, booting on the latest kernel 3. Actual results: No Volume Groups found, unable to init, right after Red Hat Nash starting... Expected results: Continue booting the system Additional info: Smolt Hardware Profile: http://smolt.fedoraproject.org/show?UUID=b0a773d5-e1ac-4d23-a413-3ff41f9dd91f
Adding "boot_delay=200" should slow down the output during driver load, so hopefully we can see what is failing. Try to see where it is loading the AHCI driver for the diska and see if there are any error messages.
Created attachment 172390 [details] output of dmesg when the machine boots on kernel 2.6.21
I tried booting 2.6.22.1-41 with the boot delay, and compared that output with the dmesg output after a successful boot in 2.6.21 (excerpt attached to this bug). I noticed that the irq in lines like: ata1: SATA max UDMA/133 cmd 0xffffc20000022100 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 21 is "irq=2296" when the boot fails in 2.6.22 (not sure if that is relevant). The problem seems to happen when trying to get the drive identification. I get lines like: ata1.00: qc_timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask = 0x4) instead of something like.. ata1.00: ata_hpa_resize 1: sectors = 145226112, hpa_sectors = 145226112 ata1.00: ATA-7: WDC WD740ADFD-00NLR1, 20.07P20, max UDMA/133 ata1.00: 145226112 sectors, multi 16: LBA48 NCQ (depth 0/32) ata1.00: ata_hpa_resize 1: sectors = 145226112, hpa_sectors = 145226112 ata1.00: configured for UDMA/133
Try adding "pci=nomsi" to the kernel command line.
Passing "pci=nomsi" to the kernel resolved the problem. Note: problem continued in 2.6.22.4-65, and this option was still needed.
Can you post output of 'lspci -n' and 'lspci -v' and information about the Motherboard and BIOS version? If a BIOS update is available, does it help?

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.
In kernel 2.6.23.9-85.fc8 I still have the same problem. If I do not pass pci=nomsi as an option the system will not find the system SATA drive and boot.
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

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.
