On the other hand, before kernel 2.4.2 I think, (not sure of the number) the kernel does not want to activate UDMA on startup even with the option activated, and this on via mb. At that time, I used to force the DMA with hdparm, and I had no troubles in dma mode 3 with that hard disk, and I can remeber that udma mode 4 was even not indicate when I try hdparm -I /dev/hdc, so I don't know why it detects dma 4, and I did not manage to change that at boot time. Another example is the hda, which is an ibm DTLA hard drive. In 2.4.2 a 2.4.3 he made the same error in udma mode4, and since 2.4.4 no troubles anymore... I find it difficult to believe that it is hardware trouble! Furthemore, I began this thread because I heard someone else on this mailing list with the same crc error and I thought the patch in ac4 was in a way to solve the dma detect fails. thanks for your help Mike > > -- > Jens Axboe
