Hopefully this is the right list. I know that IDE!=SATA, but I can't find a SATA list. Please redirect me if needed. Hardware: Lenovo T530, 64bit kernel and userland. Hadware is shown below, but 2 drives, one SSD (OCZ-VERTEX4) and one HD (Hitachi HTS54101). The SSD will lockup reliably if I do a specific mencoder command that reads MP4 files and rewrites them to another file in the same directory. The log of what happens is shown below, the drive is eventually taken off the bus. Once I reboot, it back, as if nothing happened. If I do the same command on the HD, it works, but of course timings will be different since the HD is slower. How can I tell if it's the SSD's firmware's fault, or the linux SATA/AHCI code that is buggy?
