There is a bug that has been lingering for some time that I would sure like to see fixed. We have not been able to run a serial ATA DVDRW drive on any of our machines. Any time it is connected, we get continuous repeating errors like intr 10 at 40001/40000hz, livelocked limit engage! intr 10 at 19810/20000 hz livelock removed. We have found a few past postings apparently about this issue that suggested that the problem might be related to USB. We have found no other mention of the problem being related to SATA CDRW/DVDRW drives. However, it only occurs on our machines when an optical SATA drive is connected. SATA *hard* drives work fine and USB works fine otherwise. We have tested on two different Intel machines, and an AMD64 machine, with an add on PCI SiI 3512 SATA150 controller card. We also tested with the on board VIA 6420 SATA150 controller on the AMD64 machine. The problem exists in all cases. We have also tested with 3 different SATA CD drives. The problem exists on dragonfly 1.10.1-RELEASE and we just tested today with the latest snapshot ISO image from yesterday (07/12/2008) and it still exists. We ran vmstat -i and the number of interrupts coming in from interrupt 10 were massive. We also tried setting kern.livelock_limit to 80000 but that did not help. Let me know if there is any other information that I can provide or tests that I could run that would be helpful.
