suspend to disk not working

Hi, I've just upgraded from SuSE 9.3 to openSuSE 10. In 9.3 the the suspend to disk worked very well, but it is now not working after the upgrade. (However the suspend to RAM is :) I'm not sure what info I can give but I do see in the bootmsg file that the reiser transactions had to be completed, that "Unable to find swap-space signature" and that there seemed to be some errors when accessing the disk : <4>hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } <4>hda: task_no_data_intr: error=0x4 { DriveStatusError } <4>ide: failed opcode was: 0x37 The diskdrive is a Samsung MP0402H ATA, the CPU is a centrino, and most of the other controllers seem to be intels. Anyone able to give me a pointer ? Thanks CPH
