Greetings all.   I would appreciate any incite that you can give me with
this problem.


I am sure that you have visited this issue in the past, but I have been
unable to find a resolution.  The symptoms are

            ad1: TIMEOUT - READ_DMA retrying (2 retries left) =

            ad0: WARNING - removed from configuration

            ad1: WARNING - removed from configuration

            ata0-slave: FAILURE - READ_DMA timed out


After these messages the machine is unusable until it is power cycled.



The machine can is described by dmesg below, but here is some history.  =
machine has been running FreeBSD 4.8 - 4.10 for the last several years =
two disks on the ATA0 controller. (ad0=3D Maxtor 51024H2 10GB, =
40GB) =20


I finally decided it was time to move to 5.x release.  I also decided it =
time to upgrade the disks I used a Maxtor 20GB for ad0 and WD2500JB for =
The Maxtor disk has been used before but the WD is brand new. =20


The machine is a 733 MHz Compaq Deskpro EN (Intel 815e chipset with an =
ata controller).  I have turned off all power management functions in =
CMOS. I am currently running the GENERIC Kernel as taken from the 5.4 =
install.  I upgraded to p4 but it did not help my situation so I backed =
I have searched high and low and have found a suggestion of adding a =
to the /boot/loader.conf to no avail.   I do not believe that the issue =
the ata controller, however, it could have to do with compatibility with =
250GB WD drive with FreeBSD.  I have not used the WD before but I have
tested it with Western Digital's Data Lifeguard Diagnostics as it was
installed in the box for both communication and media errors with no =


The issue seems to occur when the system has been idle for some time (an
hour or so).


Below is my dmesg output.  I do not want to reload 4.10 to have a =


 Thanks for the help.
