>Description:
I am trying to upgrade my 5.1-RELEASE to 5.2.1.
Problem I am experiencing:
instead of booting of / it prints:
WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=0
WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=0
FAILURE - READ_DMA status=51 <READY,DSC,ERROR> error=84 <ICRC,ABORTED> LBA

then prompt
mountroot>
appear.
When I type ? it prints ad0 as one of options (corrrect)
when I type ufs:/dev/ad0 it repeats previous 3 lines again 3 times.

I am unable to run 5.2.1 but 5.1 runs just fine.

I have AMD64-3200 processor with VIA chipset, running from Seagate
HD.

Few months ago I tried to boot 5.2 the same way but HD was also failing with the same message.

Yuri.

PS: PR #62687 <a href="http://www.freebsd.org/cgi/query-pr.cgi?pr=62687"/> looks similar but it was closed with the message
that wiring is bad which is obviously not true for my case (I am able to run 5.1 on that same hardware).
