One of the guys here ordered a couple of the Alienware 7700 laptops that contain the Promise PDC20378 SATA controller (PCI id: 105a 3373). It has IDE drives connected to it. Unfortunately, for reasons beyond my immediate control, we have to run RedHat Enterprise Linux 4 on the machines. It does not recognize the controller. I know Fedora 4 sort of supports it in non RAID mode. (The machines are flakey running this kernel.) Fedora 5 supports the RAID mode and seems stable. I've tried backporting the FC5 driver to the RHEL4 kernel buit it always hangs right after detecting the second drive. (libata has been changed between FC5's 2.6.15 and RHEL4's 2.6.9 making it a non trivial job.) So, do you know of anyone who has gotten the Promise 378 controller to work successfully in RHEL4's 2.6.9 kernel? Or anyone else's 2.6.9 kernel?
