Hello All, Jeff Garzik forwarded me here to get some assistance resolving a functionality regression in my sata_nv controller driver in recent Linux kernels. I have attached the same data here that I ended up sending to Jeff + others on the linux-ide list already. I assume you will probably need other different data from Jeff so please let me know if any other omitted information is required for diagnostics and I will respond ASAP.
I am using the Supermicro H8DCE motherboard. Some (not all) of the SATA channels quit working due to some kind of resource conflict when I upgrade to any kernel above 2.6.20.xx series, in my case I am running 2.6.20.21 SMP x86_64 presently. The boot error which appears in dmesg for the missing SATA channels on 2.6.23.12 is pasted below. Thanks, Matthew Hall ACPI: PCI Interrupt Link [LT3D] enabled at IRQ 46 ACPI: PCI Interrupt 0000:80:07.0[A] -> Link [LT3D] -> GSI 46 (level, low) -> IRQ 46 sata_nv 0000:80:07.0: Using ADMA mode PCI: Unable to reserve mem region #6:[EMAIL PROTECTED] for device 0000:80:07.0 ACPI: PCI interrupt for device 0000:80:07.0 disabled sata_nv: probe of 0000:80:07.0 failed with error -16 ACPI: PCI Interrupt Link [LT2E] enabled at IRQ 45 ACPI: PCI Interrupt 0000:80:08.0[A] -> Link [LT2E] -> GSI 45 (level, low) -> IRQ 45 sata_nv 0000:80:08.0: Using ADMA mode PCI: Unable to reserve mem region #6:[EMAIL PROTECTED] for device 0000:80:08.0 ACPI: PCI interrupt for device 0000:80:08.0 disabled sata_nv: probe of 0000:80:08.0 failed with error -16
