SiI3112 lost interrupts

   I bought a SiI3112-based SATA adapter (Adaptec 1210SA) and a 120Gb
drive for my computer a while ago. Unfortunately, I can't get them to
work in any sensible manner at the moment.

   I'm running 2.4.22-pre6-ac1, so by all accounts the chip should be
recognised (it is), and put into some form of DMA mode (it isn't) on
boot up. Any attempts to access the disk appear to work, but take a
_very_ long time, and cause lots of lost interrupts. 

   The relevant sections from the logs when the machine starts up look
like this:

Adaptec AAR-1210SA: IDE controller at PCI slot 00:0b.0
PCI: Found IRQ 10 for device 00:0b.0
Adaptec AAR-1210SA: chipset revision 2

   I've tried most, if not all, of the "fixes" that people have
suggested on LKML for this chipset (all the hdparm invocations, for
example), and haven't managed to change any of the symptoms I
mentioned above. Can anyone suggest any way that I can get this [for
me] rather expensive and currently useless piece of hardware working
under Linux?

   I know that Andre Hedrick has fixed some things in an unreleased
patch, but it's unclear exactly which problems he's fixed, or when the
patch is going to be released. Is anyone in a position to say whether
my problem is going to be fixed by his changes, or when that patch is
going to be released, if ever?

   Thanks,
   Hugo.
