Hello. I have a sil3132 pci-e card and a DB-88F6282-A-BP(Marvell development board based on Arm9). I compiled sata_sil24 driver as a module with a cross-compiler. But, when loading the driver, qc timeout error was occurred during ata_read_dev_id. What is wrong, IRQ or DMA ? I have 2.6.31.8 libata version 3.00 loaded. bus: 'pci': add driver sata_sil24 bus: 'pci': driver_probe_device: matched device 0000:01:01.0 with driver sata_sil24 bus: 'pci': really_probe: probing
