ad0: WARNING - WRITE_DMA recovered from missing interrupt.

I'm using emulators/vmware3 port, but I've a problem with this port on
FreeBSD 5.2-BETA, 5.1-RC1 and 5.2-CURRENT.

My configuration:
OS: 5.2-CURRENT from 2003.12.19, UFS1
CPU: P4 1.8 GHz
MB: EP-4BDAE http://web.epox.com/html/motherboard.asp?product=EP-4BDAE&lang=1

When I start vmware3 and press a button "Power On", I see the messages on
xconsole - "ad0: WARNING - WRITE_DMA recovered from missing interrupt".
After a while my FreeBSD box hangs. I disconnected in a configuration
vmware3 all devices, but it doesn't help.

When I used 5.1-CURRENT (September, October), I had no problems, except PR
ports/57465.

My ad0 drive Barracuda ATA IV ST340016A 40 GB.

My second FreeBSD box with vmware3 works fine and doesn't output any
messages.
Configuration:
OS: 5.2-CURRENT from 2003.12.19, UFS1
CPU: P3 1.3 GHz
MB:  EP-3PTA http://web.epox.com/html/motherboard.asp?product=EP-3PTA&lang=1
HDD: Maxtor 6E030L0 30 GB


What do I need to do to solve this problem?
TIA for any ideas.
