Please CC any response. Thanks.
I am having an issue with a Supermicro h8dce motherboard and failure to recognize a 5th SATA drive after upgrading to Fedora 7.
This motherboard has 8 sata ports that use the sata_nv driver.
The lack of seeing the 5th SATA drive shows up in 2.6.22 kernels, such as kernel-2.6.22.2-42.fc6 and kernel-2.6.22.1-41.fc7.
The 5th SATA drive can still be detected in 2.6.20 kernels such as kernel-2.6.20-1.2933.fc6 (I am currently using this kernel).
From dmesg, it appears the reason I am not seeing the 5th SATA drive (second SATA controller) is the following error:
Aug 30 14:08:03 alcor kernel: sata_nv 0000:80:08.0: Using ADMA mode Aug 30 14:08:03 alcor kernel: PCI: *Unable to reserve mem region* #6:1000@dfefd000 for device 0000:80:08.0 Aug 30 14:08:03 alcor kernel: ACPI: PCI interrupt for device 0000:80:08.0 disabled Aug 30 14:08:03 alcor kernel: sata_nv: probe of 0000:80:08.0 failed with error -16
sata_nv that comes with the 2.6.22 kernels appear to be version 3.4 while the older kernels comes with version 3.2 (which work). I contacted Robert Hancock directly about this and he suggested I post an email to LKML.

I can send you the complete dmesg output if you would like.
Thanks!
