Tried hint.ahci.0.msi="1" in /boot/loader.conf but it did not fix the issue fully. I only see this issue on the root pool (ada2p3 and ada3p3 are in zfs mirror) and that too mainly when I run zpool scrub. without hint.ahci.0.msi="1" there there were quite a lot of these timeouts. This issue is not present when I boot into 9.3 dataset on the same system. There are 4 disks in the system ada0 - ada3. I only see the CAM status timeout on just ada2 and ada3. ada0 and ada1 are on SATA 3Gbps link but ada2 and ada3 are on SATA 1.5Gbps. ada2 and ada3 use the internal ODD SATA port and the eSATA port respectively and they are in ZFS mirror config and have the root on them. Apparently this issue can be fixed by flashing with a modified BIOS and making the ODD sata port and eSATA port run at 3Gbps. I am not keen on using the BIOS hack. If there is no quick fix for this, I can probably stay on 9.3 given it has the same EOL as 10.1. Please let me know if any additional information is needed.
