Hi list,
I just noticed my Marvell 88SE6121 PATA controller isn't working in
2.6.25. pata_marvell.c is more or less untouched (removal of a return
in a void), but drivers/ata/ahci.c had some changes:
! { PCI_VDEVICE(MARVELL, 0x6121), board_ahci_mv }, /* 6121 */
/*
* Temporary Marvell 6145 hack: PATA port presence
* is asserted through the standard AHCI port
* presence register, as bit 4 (counting from 0)
*/
if (hpriv->flags & AHCI_HFLAG_MV_PATA) {
! if (pdev->device == 0x6121)
! mv = 0x3;
! else
! mv = 0xf;
dev_printk(KERN_ERR, &pdev->dev,
"MV_AHCI HACK: port_map %x -> %x\n",
port_map,
port_map & mv);
port_map &= mv;
}
I'm using AHCI for an Intel ICH controller which runs two SATA hard
drives and one SATA DVD drive.
My dmesg used to look like this:
ACPI: PCI Interrupt 0000:03:00.0[A] -> Link [LNKA] -> GSI 10 (level, low) -> IRQ 10

and now looks like this:

ata8: SATA max UDMA/133 abar m1024@0xfe9ffc00 port 0xfe9ffd80 irq 16
ata9: DUMMY
ata7: SATA link down (SStatus 0 SControl 300)
ata8: SATA link down (SStatus 0 SControl 300)
So, I guess the AHCI driver has taken over for the PATA controller,
but something must not be right... The controller doesn't see link
and the drive doesn't show up anywhere, but the BIOS sees it fine.
Any ideas? Should I disable PATA_MARVELL?
Thanks,
Mike
