Not extremely but still astonishing. As a consequence, we have created a number of patches to our 2.4 kernels that did improve some things, such as the backport of the REPORT_LUNS scanning from 2.6 and a number of boot/module parameters that allowed users to influence how the scanning is done. http://www.suse.de/~garloff/Linux/scsi-scan/scsi-scanning.html With kernel 2.6, the REPORT_LUNS is standard for SCSI-3 devices, but still many arrays exist that report as SCSI-2 and will require BLIST_SPARSELUN|BLIST_LARGELUN. An alternative to the blacklist is to offer boot/module parameters again. This is what the following series of 6 patches do. Most don't really depend on each other, but they'll only apply cleanly in the order sent. I did not yet compare our 2.4 blacklist with the 2.6 one; I'll port our additional 2.4 entries to 2.6 soon.
