On a 9.0-RC1 system I am seeing ahci timeout messages like this: ahcich3: Timeout on slot 2 port 0 ahcich3: is 00000001 cs 00000000 ss 00000000 rs 00000006 tfd \ 40 serr 00000000 cmd 1000c213 ahcich0: Timeout on slot 24 port 0 ahcich0: is 00000001 cs 00000000 ss 00000000 rs 01800000 tfd \ 40 serr 00000000 cmd 1000d813 on VM on Parallels Desktop 6.0.12106 for OS X The messages appear to be quite benign, and the system resumes after a couple of seconds. 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.
