Ah, damn, forgot to mention kernel versions. kernel-2.6.15-1.2025_FC5 is confirmed as a problem. kernel-2.6.15-1.2032_FC5 will be tested shortly (but not holding my breath). All kernels before this (from fc5t3) haven't worked. Kernels before fc5t3 also didn't work (although I think there were one or two kernels that did work at one stage. Don't quote me on this). A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you. Okay, I've tested this with 2.6.18-1.2200.fc5. If I remove the hdc=noprobe from the boot command line, the DVD player works, inserted media is detected (it shows up on my gnome desktop) BUT it is mounted as /dev/hdc. If I retain the hdc=noprobe, then inserted media isn't detected and the drive isn't mounted. This seems to be a regression from the last kernel which would detect media and mount it as scsi when given the hdc=nomount command. Not sure what to set status too? And it still seems to be needinfo Is this a SATA drive ? (If so, is it set to 'combined' or 'legacy' mode in the bios?) Can you attach the output of dmesg ? Yes, it is a SATA drive (or at least I believe it is. Setting hdc=noprobe sees the drive mounted as a scsi device and also sees it performing much better/faster - how would I tell for sure). I don't believe the bios on my Dell Inspiron 9300 has this option. I've been told to look for it before and have, but haven't been successful in finding it in the bios settings. I'll try to attach dmesg when I get a change. I've been runnning FC6 of late so haven't been using FC5 much. On this, I still have to pass the hdc=noprobe option in FC6 to get my DVD drive to work as a SATA device (mounts as scsi) and to get the better performance. I'm not sure whether this is addressed in FC5, I've moved to FC6 at this stage and I'm testing FC7 (rawhide). I noticed that I no longer need to pass hdc=noprobe in fc7 (and in fact, while I told the installer to do this, it never appeared in /boot/grub/grub.conf). I'm not sure whether recent upgrades to the kernel in FC6 have resolved this issue, but I guess I should try again soon. Is it time to mark this bug resolved? I used to have these problems as well, but I haven't had a single issue like this in F7. I suggest marking resolved, too. |
