Now I've tried the above suggestion, it does not seem to solve anything on Ubuntu.. I've tried adding it: 1) In the /etc/modprobe.d and reconfiguring initrd 2) Adding it on the commandline to the kernel boot parameters. 3) Even tried the old scsi_max_luns the same way.
The aic7xxx module gives this output: Jul 11 08:06:20 atlas kernel: [ 100.649227] aic7xxx: Unknown parameter `max_luns' I've tried the same process on the "scsi_mod"-module .. as tha IBM article suggests. Thus it seems as it has been renamed again or there is another parameter that interfers with this setup. Dmesg from "scsi1" the problematic controller..
