Hello,

today I've tried to install Slackware 12.0

As the installer just "skipped" some install steps, I tried to find the error.

The problem seems to be unreadable parts on the DVD:

But the DVD is OK. I've checked the MD5sum directly from disc on the same system using the same DVD drive.

dmesg says:

The kernel, used on the Slackware setup disk, uses SMP, but my hardware doesn't support this (get error on dmesg). May this (SMP kernel on non-SMP system) cause such bugs?

Is this a known bug? How could code, which breaks DVD access, get into stable 2.6.21.5?

I don't think this is a bug, the drive was told to read a sector and returned error SK=03, ASC=02, ASCQ=00 which is "NO SEEK COMPLETE", in other words it couldn't find that sector. Could be that the disc is marginally readable and only sometimes causes read errors.
