insert music CDs floods dmesg
 
I had a terminal open waiting to catch these messages that spam dmesg.
Simply inserting a music CD into /dev/sr0 or /dev/sr1 gives me this:
Code:

It's literally thousands of lines, making any "dmesg" output useless.

My Google fu isn't helping ...

This is on a fresh Slack-13.1 install today, with all packages from patches updated.

I had something like that happen with stdout, but that, I think was when I tried to use the discs; probably because they...the discs...had problems. That is all I can say on that. Once, there was a disc that showed something like that on stdout when I tried to mount it...the disc was data...turned out the disc had a scratch like a spot

Bruce Hill 10-12-2010 08:18 PM
Hey PenGUiN_6_1,

Thanks for your reply.

This is only happening with music CDs, so of course they're not mounted.
It does not happen with data CDs, or with DVDs. The discs are originals,
and not scratched. The CD-ROM drive is about 8 years old, but the DVD is
much newer ... maybe a year or so, but I haven't checked. They both work
fine doing what they were designed to do.

It does not happen with Gentoo on the same computer.

The output starts after the drive tray is closed, and then the CD-ROM
starts spinning up the disc. Maybe there is some script in Slackware
that is trying to read the disc, though personally I have no automount
stuff to my knowledge.

I'll have to check that when I get back home ... on the way to Vietnam atm.

I think I get similar messages on boot when I have an audio CD in my drive. I don't have any problems with the CDs, or the drive.

glorsplitz 12-25-2010 10:13 AM
@Bruce Hill, did you ever get anywhere with this?

Yes, I tried many things on Slackware 13.1, and nothing fixed it. There were
also several other problems with Slackware 13.1.

I tried 2 other distros on the same box, and neither of them had that problem.

Now it is permanently fixed ... I removed Slackware and installed Gentoo.

glorsplitz 12-27-2010 08:53 AM
thanks for your reply, not kind of fix i was hoping for

cd/dvd drive works fine, log messages for audio are more of a nag

i was thinking of writing script to delete annoying log messages

cheers!

glorsplitz 12-28-2010 08:42 PM
if anyone is interested
 
screwed around with this a little more

inserted commericial audio cd

cdparnoia -vsQ (does check of drive, cd, lists cd contents), messages/syslog flooded, see above samples

cdparanoia -B 1 (rip track 1) no log flood

did couple more tracks, no log flood

ejected cd, repeated above cdparanoia stuff, new log flood

ripped couple more tracks, no log flood

seems after initial access to audio cd, logging stops
