This is just a 'me too'.
I've experienced the following on 2 seperate and very different i386
ad4: TIMEOUT - READ_DMA retrying (1 retry left) LBA=1520671
ad4: TIMEOUT - READ_DMA retrying (0 retries left) LBA=1520671
ad4: FAILURE - READ_DMA timed out LBA=1520671
That was on an Intel i815 based board running a Celeron 1.3 but with a
Highpoint HPT370 IDE RAID controller. The above disk is a Seagate
Barracuda 7200.10 80GB, and one of a pair (both have the same problem).
The error occurs just after disk detection at the end of the boot where
normally it would mount / and start running rc
The second system is a Dual P3 Serverworks system with an IBM 60GXP
Deskstar 40GB disk connected to the onboard UDMA33 controller.
Disabling DMA in loader.conf does the trick and allows both machines to
I have tried different drive combinations and controllers but to no avail.
Neither of the systems are required for use just at the moment, so I'm
quite happy to test patches once they're available, or provide further
details as required.
