Hi Chris, It was a good idea but it doesn't resolve the problem...
I add my card into the dma_black_list of the libata to force DMA disabled and the problem seems to no more appear...maybe PIO is so slow that the data has no time to be corrupted... But I can NOT affirm that the problem is the DMA.
I try the linux kernel 2.4,2.6.11, 2.6.12 and 2.6.13. More I try 2 different toolchains and the problem persists...
Another idea??
Thanks,
David

Disable prefetch in lib/memcpy.S and see if that helps. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
