How much memory is installed in this machine? If more than 2 GB, try the x86-64 live CD again with "mem=2G" appended as kernel parameter on the boot loader's prompt (if that is possible with the live CD), or with RAM physically removed so that no more than 2 GB remain. (I am alluding to bug 435550 here which was about TSB43AB22/A.) Could you test an actual Fedora installation (F12 or Rawhide) with the current Rawhide kernel package? This would be a 2.6.33 pre-release kernel which contains a change that could fix this issue. On F12, you get the Rawhide kernel with # yum --enablerepo=rawhide install kernel (Or at least I think so; I don't have Fedora myself.)

Stefan - The machine in question does have 4G of memory. The mem=2G option does indeed seem to fix the problem. I'll try to test the updated kernel. I hope that kernel-2.6.33-0.20.rc5.git0.fc13.x86-64 will fit the bill. One other odd thing that I noticed about this problem - it no longer appears to be completely reproducible with the stock x86 settings. It appears to be dependent on which PCI/PCI-Express cards are installed (and possibly which PCI slot gets used). For instance, the problem occurs when the Firewire card is in PCI slot 4, but not 3. If I add my PCI-Ex graphics card, the problem goes away. I will try to test this more. (In reply to comment #3) > It appears to be dependent on which PCI/PCI-Express cards are > installed (and possibly which PCI slot gets used). Perhaps the presence or absence of other cards influences the probability of allocations (of firewire-ohci's dualbuffer DMA descriptors) landing above or below the 31 bit address barrier which is problematic for TSB43AB22/A and evidently TSB43AB23 too. If you have the means to test a kernel-2.6.33*.fc13.x86-64 on a hardware configuration that would get no video or only corrupted video under F12/x86-64, that would be appreciated. (If successful, it would be green light for a fix patch that I have in mind.) Upstream bug: http://bugzilla.kernel.org/show_bug.cgi?id=13808 Proposed patch: http://lkml.org/lkml/2010/1/26/284 The fix for this is queued for 2.6.32.8 as: firewire-ohci-fix-crashes-with-tsb43ab23-on-64bit-systems.patch upstream commit 7a481436787cbc932af6c407b317ac603969a242 This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '12'. 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 12'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 12 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 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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. |
