ATA DMA problems with recent -current

Hi all,
I just updated my -current kernel to today sources -- the previous
kernel was from Oct 11. With the new kernel I'm getting ad0 ATA DMA
timeouts, which get worse when I stress the drive.
The timeouts look like this:
ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=3952128
ad0: TIMEOUT - READ_DMA retrying (0 retries left) LBA=3952128
ad0: FAILURE - READ_DMA timed out
g_vfs_done(): ad0s4 [READ(offset=1746108416, length=65536)] error=5
vnode_pager_getpages: I/O read error
At first, they are occasional and only happen sometimes -- in fact I
didn't notice them when booting the first time.
However, I then tried to unpack the ports.tar.gz file, like this:
$ gzcat ports.tar.gz | tar xf - -C /usr
... which, after unpacking a couple of files, hanged, getting
WRITE_DMA timeouts from the kernel.
All write attempts to the drive from that point failed. I rebooted the
system, and the filesystem appeared dirty to fsck the next boot.
Some information from the new kernel -- the full dmesg is at the end
of the message:

In contrast, my previous kernel, compiled Oct 11, works perfectly with
ATA DMA. The same tests that fail badly on the new kernel (like
unpacking ports.tar.gz) complete without any problems on the Oct 11
kernel.

Here is a full dmesg of the new kernel. In both this kernel and the
working Oct 11 kernel, my "aoa" driver for sound is enabled. This is
the only modification with respect to a CVS GENERIC kernel.
