ad0: WARNING - READ_DMA interrupt was seen but timeout fired LBA=xxxx

Hi,

When booting with ACPI enabled with RELENG_5 or HEAD of today (or 5.3-BETA6) I get:

ad0: WARNING - READ_DMA interrupt was seen but timeout fired LBA=xxxxxx

This happens during somewhat heavy disk activity (I use fsck to test) and it just keeps repeating the error with the same LBA. All disk activity just fails.

When I boot RELENG_5_2 of today (or 5.2.1-RELEASE) _with_ ACPI enabled, it works fine.

I saw a sprinkling of messages about this error in August on this list, and a single one in September, but nothing since then.

What can I do to help with this issue?

Hardware is an HP compaq nx5000, putting the dmesg for 5.3-STABLE below.
