Hello,
I see the sata_sil24 / Sil 3132 fail on my system.
Linux 2.6.38
Silicon Image 3132 Mini-PCI Express card on the Freescale PowerPC
e500v2 based SoC on the P1020RDB board
Intel SSD attached.
MSI disabled already fails during IDENTIFY phase.
MSI enables does ok for small transfers, but fails on larger transfers.
Inspecting the driver source, I notice PCI flushing reads are missing
at points I would expect them.
static int sil24_exec_polled_cmd(struct ata_port *ap, int pmp,
const struct ata_taskfile *tf,
int is_cmd, u32 ctrl,
unsigned long timeout_msec)
{
<...>
writel(irq_mask, port + PORT_IRQ_STAT); /* clear IRQs */
<...>
/* restore IRQ enabled */
writel(irq_enabled, port + PORT_IRQ_ENABLE_SET); <----------------
PCI flushing read required ??!
return rc;
}
modprobe sata_sil

That stalls, I see the controller fail. See dmesg below:
