I've found another piece of the puzzle. The problem isn't strictly with optical media. The problem appears to affect ALL removable media, including flash devices.
|
Well, I'll add my 2 cents. I run Slackware64 13.1 and Slackware 13.1 (IDE/PATA controllers, 2.6.33.4-generic), plus Xubuntu and Ubuntu (sata controllers, 10.04 LTS, 2.6.32-22-generic), and I have this issue on all of them. I can automount all DVDs, all commercial pressed CDs, but my burned CDR and CDRW that are known good on Slackware 13.0 don't always automount. I have a 2 year old data CDR that mounts fine, but recently burned CDR (from Slackware 13.0) are about 75% fail to automount. Whether KDE, Xfce, or Gnome is used is not important. Explicitly mounting as root or using fstab works ok. This problem started once I left 2.6.29 series of kernels so its not my disks and it is not my hardware. I also have WinXP, Vista. and Win7 systems that automount all disks just fine. Googling shows a lot of activity with some fixes/work arounds that do not fix the underlying issue
This is a weird bug that I unfortunately no longer have the skills to track down (last code was Z80 assembly on CP/M-80) and it is driving me nuts. Sure, I can do it the "old fashioned way" but why should I not have automounting automation in the 21st century? |
tpreitzel, nope, for me every USB stick and external USB hard drive (fat32, ext3 and NTFS) automount just fine here.

Your scenario isn't exactly equivalent to my experience, though. For sure, this bug (bugs?) is driving a considerable number of people over the edge. :) |
Hi,
all the questions about problems with mounting optical disk are probably due to the kernel bug. But it is rather hard to get the kernel bug message in syslog. So be patient. Sooner or later should be fixed. OK! Let try to fix your problem: 1. Did you install slackware from CD-ROM ? a) yes, I did. Ok, my advice: reinstall your system (oh no) but only with base system (A series) and check if you are able to mount manually CD-ROM b) no, I did'nt. Ok, try to use the install cd-rom. I guess it will work, then go to the point a) |

Lastly, precisely what kernel bug are you implying? I just upgraded to 2.6.33.6 and the problem remains ... Periodically, I work with Slackware64 13.1 and add software so I won't have to do all that work later when the next version of Slackware64 is released which hopefully will fix this nightmare. My primary system remains BW64 13.0 until this problem is fixed. * I may try the A series at some point ... maybe. More likely, I'll just periodically update SW64 13.1 until a new version of Slackware is released... |
I know mu post is not very useful.
My system once reported a kernel bug. I regret I didn't post it. I think that at this moment all systems with new kernels 2.6.33.x should be used carefully, always have up to date backup your important files. I know this sound not very nicely, especially in the view of that slackware is supposed to be stable (for some people it is stable), but now I am still testing slack 13.1. At the first time I installed slack on jfs file system, but next decided to reinstall on ext2 (for me it seems to be more safe). I don't want to blame slackware. I want to use it and I use it. Fast inspection of the forums for other distros shows that each new release has quite similar problems (excluding debian, centos etc... they use kernels 2.6.2). |

I'd say that since Pat V and the set of Slackware maintainers/contributors did not see this issue, then I don't see how they would know the problem existed if the set of folks with the problem didn't whine about it. (Hey, I whine when I have problems with something.) If you see problems in -current, you really, really, really need to report them. Pat's a nice guy who has some pride in Slackware. Who would want to release a broken distro? |
I haven't had time lately to pursue this issue, but I'll say that it is still very much a problem on my system. I have installed the latest stable kernel (2.6.34.1) and same result.
To summarize again: The problem does not occur on Slackware 13.0, it was introduced with 13.1. Re-install 13.0 and the problem goes away. It doesn't matter whether you use a supplied (pre-compiled) kernel or compile your own. Every kernel release that I've tried has the same result. It doesn't matter if you use AHCI or not, same result It doesn't matter if you have a fstab entry for /dev/sr0 or not. I, for one, have NO problem mounting audio cd's, USB sticks, or flash cards, just cd's with a filesystem (ISO9660). There are MANY threads all over the web on this issue, not just Slackware but other distros as well. Nobody appears to have solved it. |
yeah, this is a weird one. I just double/triple checked and booted into Slackware64 13.0 multilib and had no problems with any of the CDs. In fact, this is the 1st time automatic mounting in Xfce and KDE didn't work in quite some time. The work around is simple: use "mount" ... well fine ... that "solution" is all over the 'net. However the core issue is still there. I now have issue with Slackware 13.1 (both types, various boxes), Ubuntu, Xubuntu and Absolute Linux. These are all "full" distro installations with the latest updates.
The kicker is its ONLY CDRs in my system and not even all of them: pressed, old, new, burned today, burned whenever. And NONE of these CDs has any problems being automounted on WinXP, Vista or Win7. Something broke along the way to 13.1 Is it the kernel? udev? The driver switch and /dev/srx? consolekit/policykit? Does /etc/rc.d/rc.autofs need to be set executable and if so why do DVDs automatically mount ok? I don't run a server so a well behaved desktop GUI is important to me. The CDs mount ok manually but that is an extra step I did not need in the past. I assume the Slackware team is aware of this and that not all of them is so "old school" that they spend all day at the CLI with mount/umount. So what say you, gang? How do we fix this? |
I also have a machine running Slackware 13.1 that won't mount CDs.
I'll see something like this from dmesg Code:
sr 1:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08 Manually mounting the CD as root works. Thumbdrives work. The same hardware running Slackware 13.0 works. This is an old PIII Coppermine, running the generic smp kernel. Code:
