What other info can I provide to | debug this? I'd like some clarification. Does the system boot sometimes and other times is doesn't? Once the system is up does it stay up for a while? It doesn't seem like you are not using RAID. I have a couple more ata bug fixes that I need to roll into another patchset. It fixes a bug in which DMA transfers have not been cancelled when the controller is reset. I fixed another panic situation in version 8 that happens on boot if you have a bad sector at the beginning of the drive. I'd wait to version 9. I should be able to get that out later today. Another thing that you might want to do is monitor dmesgs for any ata/ad errors while the system is running. Most panics happen later after the first error message. Also you could try looking at /var/log/messages. Thanks, Doug A.
