Slackware64-current doesn't read cd-r disks as well as slack 12.1 does(?)

I have slackware 12.1 installed along with slackware64-current.
I have bunch of old cd-s with data backups. Yesterday i had to copy few files from them, but slackware64-currents hal just ignored the cd-s spitting out some errors in /var/log/messages and /var/log/syslog.

I rebooted to slackware 12.1. There, hal detected, mounted these disks with no problem. Copying succeeded also. That's all. What to expect? Can newer software degrade cd/dvd-drives reading performance?

I would look at the driver/firmware for the device. Confirm the correct driver is loaded for your device when using '-current'.

This just recently started happening to me after one
of the updates (using -current 32bit). The CDs used
to work just fine and now they do not automount and
I get similar errors in the log.

For me, manually mounting them as root using the
"-t iso9660" option works just fine.

Searching google for:
"kde4 lost automount" and "hal automount util-linux-ng"
comes back with a few hits that seem similar...

But it is still not working here...
