I forgot: this bug is on Fedora 8 (2.6.24.*) and Fedora 9 (2.6.25.*). The key part of dmesg being this: ata2.00: simplex DMA is claimed by other device, disabling DMA I'm not sure what the hardware limitations are here, (perhaps Alan can clue us in). It looks like you have the DVD drive as the primary master, and hard disk as secondary. I wonder if reversing this situation would 'solve' this ? Alan ? Yes, I have ASUS A9RP and it is true that DVD is on 1st master and harddrive on 1st slave. I checked this in BIOS. But i notice that UDMA works perfectly on kernels before 2.6.24. Fixed upstream now - its a combination of two bugs, one Fedora bug that has been reported since early FC8 and one kernel thing which triggers a hardware funny. Fix is in 2.6.26-rc, but the right fix for this (and some other fun) is to stop loading pata_acpi *before* chipset specific drivers. Ok, thanks, but how can i fix it temporarily until new kernel is released. anaconda just runs udev for loading modules these days. Which then invokes modprobe of the modalias. Of course, all matches for a modalias are "equally" good as far as anything can tell other than doing explicit module name hacks in modprobe :-/ But to modprobe Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping 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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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'. 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 9'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 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. |
