Re: Booting loops (Downloading SCSI SCRIPTS)
safe:y implies mpar:n
(see ${your_kernel-2.2.17-dir}/drivers/scsi/README.ncr53c8xx line 862..884)
Somehow someone added, for some reason, the ncr-810 safe:y line.
This together with the fact that there is a shortage of lines at the
boot screens, made suggest a minimal change, just to be able to boot.
Then in a production environment, safe:y is grossly suboptimal.
But at least, we made it install.
