[aclug-L] Re: Driver load order, two scsi adapters

["Greg House" <ghouse@xxxxxxxxxxxxx>]

Are you saying I could still use the kernel module auto-loader (with the
qlogic driver as a module and the sym driver compiled in)? I haven't tried
it, things have been working fine using insmod in one of the startup files.
