Subject: SiI 3512 Serial ATA Controller - kernel 2.6.23

hello

I have a problem with a serial ata controller
that uses a SiI 3512 chip.

when I'm trying to add a device thats on the 3512 controller 
to the array that I have, it give me lots of errors in dmesg
like this:

ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x2400000 action 0x0
ata3.00: BMDMA2 stat 0x8652001

ata3: hard resetting port
ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata3.00: configured for UDMA/100
...........

is this a bug, is there a patch, or a workaround ? 
I desperately need to grow the array (which is a raid5) with 
the new harddrives :(

10x for help
