problems with scsi

hi all,
sorry, this may be out of topic:
i have a dual-ia64 with a qlogic qla12160 scsi controller. this talks to an ibm ddys-t18350 harddisk.
i cant get it running since after "modprobe qla1280" kernel says: "sda: unsupported sector size 8704." no other complains before or after.
the disk works fine on a ia32 with a symbios u160 controller. do you know any hints how i could track down the problem? or could you forward me to someone that maybe knows? i use suse 7.2 ia64, currently on a 5 jear old ide disk. now i got double the size ram compared with hardisk size. thanks
