Hi,

while playing with grml-daily (2010-09-05) 32-bit sid with 2.6.35-grml kernel, 

I discovered the following warning/call-trace in dmesg:

A similar bug can be read here [1].

NOTE:
As this could matter... grml-daily was burned on an 80min CD-R and started from
a CD-/DVD-drive, here you can see the wodim command-with-options:

$ wodim dev=/dev/scd0 speed=8 -dao -overburn -v grml_sid_latest.iso

Hope this helps fixing the problem.

Kind Regards,
