Probs burning CDs

[Steffen Grunewald]

We're currently running one machine under kernel 2.2.5 (SuSE 6.1).
We're getting byte differences between the original data (on HD)
and the CD data.

HW: Pentium class machine (1/2 yr old), 
AIC-7890/1 Ultra2-LVD, Teac 55S recorder at speed 4.
Kernel 2.2.5, aic7xxx driver 5.1.13/3.2.4
mkisofs 1.12b5
cdrecord 1.8a22

the mkisofs image is OK, the differences come from the path of the
data to the CD. I suspected the iso9660 fs layer first, but reading
back the whole image from the CD produces a different image file :(

data corruption groups into 4-bytes clusters mostly, but there are 
also longer blocks which differ (the 4-clusters are interleaved
by 4 bytes which don't differ)

Any idea for fixing ?
