I have read that others had this problem before. I
just write this report for you to know.

When I installed FreeBSD 5.3 R, I get some errors
like this, but I could end the install:

ad0: WARNING -READ_DMA UDMA ICRC error (retrying request) LBA=5313599
ad0: FAILURE -READ_DMA status=51<READY,DSC,ERROR>
error=84 >ICRC,ABORTED>
spec_getpages:(ad0s1a) I/O read failure: (error=5)
................


I have solved the problem disabling DMA:
hw.ata.ata_dma="0"

(I previously tried disabling ACPI with no success,
and playing with BIOS LBA, LARGE, NORMAL settings
at the BIOS with no success).

Now ad0: works in PIO4 mode and everything is fine,
previously , it was UDMA33. Now there are no errors.


There's you and me now. I have this problem with two
of my PCs. I don't know yet of anybody else who has
these problems.

It's indeed a serious problem, but too few people
running 5.3 seem to suffer from this.

Have you tried with 4.11?
I bet that would not generate these problems.


Thanks, I see that we are not alone!

I have not got a 4.11 CDROM here. I could test it on 4.10 if you think it is important, I have a 4.10 CDROM here. My internet is too slow to dowload a full CDROM at home. I can download 4.11 install CDROM on the computers at University if it worths the effort.

Please let me know.

Ramiro.

Rob.
