Please try "pata_dma=0" After I boot with pata_dma=0 parameter I don't have again the message "Unknown boot option ...". However DMA is not disabled for PATA optical device. After more findings I found out that what work is to put the following line "options libata pata_dma=0" in /etc/modprobe.conf, remake initrd image and boot with new initrd. 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 This bug appears to be resolved and I am therefore closing it. If I have erred, please forgive me and re-open with any additional information you are able to give. I will then try and assist you if I can. Cheers Chris No, this bug is not fixed in kernel kernel-2.6.22.5-76.fc7 (neither in kernel-2.6.22.4-65.fc7). Okay, sorry to hear it Mihai. However you will be glad to read the following: http://www.redhat.com/archives/fedora-kernel-list/2007-September/msg00011.html therefore I would be grateful if you could test with a rawhide kernel and report back. Cheers Chris The new pata_dma patch is also in F7 kernel 2.6.22.6-81, which is now in the updates-testing repository. Mihai, can you test please and close if fixed for you. Cheers Chris Sorry neither F7 kernel 2.6.22.6-81 from updates-testing repository does not work. I will try a rawhide kernel as soon as I can. The same with last rawhide kernel 2.6.23-0.185.rc6.git7.fc8 In what way do these not work? The bug was filed indicates that the boot parameter: libata.pata_dma=0 does not work. Is this really still the case? Apparently you need to add the parameter to the module when it gets loaded, like in comment #2. This makes it pretty useless for distro installs unless libata is built into the kernel... Ref comment #10: yes the bug is still present in all that kernels Ref comment #11: also this is problem if you want to upgrade firmware for a DVD with a LiveCD/LiveDVD booted externally Yeah, without support in anaconda this parameter is pretty much useless. And since upstream hasn't decided exactly how it will work yet, it should probably just be removed. This option was made available for F8 release final with support for anaconda. I am therefore closing this bug to reflect that. Please re-open if current kernels do not perform correctly for you. Also, the option is now "libata.dma" instead of "libata.pata_dma". |
