Hi,

I am running a 5.2.1-RELEASE router/firewall and I am getting messages
such as:
ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=7593671
ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=10216223
ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=9099251
ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=10592607
ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=7206207

In 13 days of uptime I have got 13 similar messages in dmesg, and no, I am 
not getting them at a constant rate.
The box has almost no load on it's hard drives.

I though I would just report it, maybe it is useful to someone.

For further information I am also including some more output from dmesg:
