Reassigning to correct owner, kernel-maint. A quick fix procedure for this bug for current fedora users is available at this link: http://forums.fedoraforum.org/forum/showthread.php?postid=556704 Can kudzu be altered to make these adjustments (probably not in terms of grub) or is there a pure kernelspace solution? The procedure above appears to work with no ill effects. Hi, I updates to todays rawhide, so fc6test2 is no more accurate. I followed the instructions and it got worse. The DVD runs in DMA, but is highly unrealiable. Read Errors, hangups, ... So I disabled the libata stuff again. cu romal We had similar problems with our range of Dell Precision laptops. It is a problem for getting linux accepted as a desktop among our employees. The proposed solution from Fedora forum, that Casey Dahlin pointed out, (adding combined_mode=libata to grub) did work for my Dell Precision M65, and seems after two weeks use to be stable. I hope his suggestion about using this workaround can be applied in future updatas to Fedora. In case it might assist in improving Kudzu, here is the technical information about my tested system.

I have two SATA hard disks, and one PATA DVD-R drive. In my BIOS configuration, I changed my IDE configuration from Auto (which was defaulting to Combined mode) to Enhanced mode. Now all my DVD-R drive is running in DMA mode properly. I thought I would pass this along in case it might help someone else experiencing this issue. I am also hitting the problem here. Matsushita UJ-841S drive, Toshiba Satellite A100-847 laptop. Running Fedora Core 6 now. 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 http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! Closing per previous comment. If you can provide the requested information, please feel free to re-open this bug. |
