But on another system, 10.0-CURRENT as of a few days ago with a ZFS filesystem on a SATA disk, when a ahci timeout message appears the system freezes, although it is possible to switch consoles with alt-Fx Are there any timeout values I could possibly increase to make these messages go away? Regarding ZFS, yes I know it makes no sense to run it on a virtual disk. I'm doing it for fun and educational value as well as testing 10-CURRENT out.
