Since I had a mixed system at that point, I set hw.ata.ata_dma="0" in /boot/loader.conf and completed the install. After a good boot to verify everything was working, I flipped hw.ata.ata_dma back and rebooted. The corrupted sync message scared the heck out of me: Waiting (max 60 seconds) for system process `vnlru' to stop...done Waiti Synncgi n(gm adxi sk6s0, svencoodnedss )r efmoari nsiynsgte.m. .pr1o0c ess `syncer' to stop...8 7 8 3 3 3 1 0 0 0 0 done And after the reboot, the READ_DMA timeouts were back. I installed sysutils/smartmontools (output attached in case it's usefull) The only "odd" think I can think of about my system is an unusually high HZ value (2386) I'm building a kernel now with 1000 to check if that makes a difference.
