SCSI_DELAY in the code didn't change between 9.1[1] and 9.0[2] neither did it in the configuration for the GENERIC kernels[3][4]. On both occasions (9.0 and 9.1) I used the GENERIC kernels and I didn't change this setting. I will give it a try as soon as I can, but it still seems a little strange to me that this process takes longer in 9.1 for no apparent reason Thanks.
