Cannot burn without strace on 2.6.8-rc3-mm1

Ok, thats strange:

Just switched form 2.6.7-mm5 to 2.6.8-rc3-mm1 However I cannot burn with cdrecord. cdrecord -v dev=/dev/hdc -dao driveropts=burnfree -data /files/Pakete/KNOPPIX_V3.4-2004-05-17-DE.iso gives:

alex@t40:~$ cdrecord -v dev=/dev/hdc -dao driveropts\=burnfree 
-data /files/Pakete/KNOPPIX_V3.4-2004-05-17-DE.iso

Try:
LD_ASSUME_KERNEL=2.4 cdrecord -v dev=/dev/hdc etc etc etc.

Not that this is correct, but if that helps it will have narrowed down the problem. Also show 'ldd cdrecord' and 'ldd strace'.

I've seen a problem before that was solved by strace and it had to do with the TLS NPTL stuff.
