persisting ATA problems

Hi,

I am running VIA8237 ata controller with BETA6 from 02.10.04 and in
dmesg still have the following errors:

ad0: WARNING - WRITE_DMA interrupt was seen but timeout fired LBA=846959

I thing it will good with beta6, because some changes was made on ata,
but not.

Thanks for help.
