• If you know the device name where grml is booting from try booting via: "grml bootfrom=/dev/sda1" (assuming the /dev/sda1 is your CD/DVD device booting grml). Does this improve your bootup time? If so we could spot the device which takes just to long for scanning.

After the usual 3:30 delay it read "mounted live system on /dev/scd0" so I tried (as you suggested) grml bootfrom=/dev/scd0 but this did not help, sorry.

Ok

...

• Blacklist modules: when booting finished check out dmesg output and if there any noteable error/warning messages

There are several error messages like this: a) many lines saying sr 6:0:1:0: [sr0] Sense Key: Medium Error [current] sr 6:0:1:0: [sr0] Add. Sense: L-EC uncorrectable error

b) many lines like this Buffer I/O error on device sr0 end_request: I/O error, dev sr0, sector 1380478

[...]

This looks like a broken CD.

Please check the CD using 'readcd -c2scan dev=/dev/cdrom'.
