Description David Milburn 2005-05-04 16:54:27 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2

Description of problem:
Dell reports that a SATA host configured with a master supporting lba48 and a slave that does not support lba48, renders the slave inaccessible. The customer has supplied a patch that will not set the host's max_sectors when a drive supporting lba48 has been detected, since this becomes the default max sectors for any drives probed after that point. 

Version-Release number of selected component (if applicable):

How reproducible:
Couldn't Reproduce

Additional info:

I patched the kernel-2.6.9-6.37.EL with the customer patch, booted kernel on i686 system with a Promise SX4 controller and a SATA ST3160023AS to verify that it was still accessible.
