Hi,

I've read about some ATA DMA timeout problems recently here.
I just want to tell you, I've got same problems recently.
I had to install the kernel.old back to get rid of severe
problems.

Affected kernel version:
FreeBSD 5.4-STABLE #0: Tue May 31 00:19:34 CEST 2005

Last known working version:
FreeBSD 5.4-STABLE #0: Mon May  9 00:50:46 CEST 2005


Problems with yesterdays kernel:
ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=200649278
ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=225457534

The system was slowed down. I noticed it while starting
some desktop applications.

Then I ran cvsup to update my ports tree. This led to a
slowdown, which looked like the system was frozen. It was
still moving (a bit), but I lost my patience and pressed
the reset switch.

Martin
