I've probably answered this about 40 times now, but here it is again. The Dell PowerEdge 6300 machines use the SC450NX chipset, and the particular version that they use is sensitive to EISA/VLB port probes. So, when the aic7xxx driver probes for VLB or EISA cards, it has a chance of causing the machine to black screen and either hang or reset. The fix to this is to use the aic7xxx driver, but to load the module with the option aic7xxx=no_probe. So, for a Red Hat Linux 6.0 install, you would need to start the install in expert mode (so that the install program doesn't automatically load the aic7xxx module for you without any options), tell it that you have a SCSI controller, select the 2740, 2840, 2940 Adaptec SCSI controller, then select Specify Options, then type in aic7xxx=no_probe and it should work fine. The install program will remember this and when it writes the /etc/conf.modules file it will include a line to preserve that option in all future instances. > It appears that as of kernel 2.2.1 the aic7xxx 5.1.10 driver is standard, > and 5.1.11 is the latest.

For speed and accessibility I'm now making my web site my primary place of distribution (it isn't nearly as heavily loaded as the ftp server is). That means you can find the latest aic7xxx stuff by going to http://www.redhat.com/~dledford/aic7xxx.html -- Doug Ledford <dledford@redhat.com> Opinions expressed are my own, but they should be everybody's.
