Hi all, This is with: FreeBSD zfs.digiware.nl 9.1-STABLE FreeBSD 9.1-STABLE #59 r245340: Sun Jan 13 06:49:37 CET 2013 I removed my WD USB disk, and it started to reboot just fine.... And as such I think it is a combination of USB storage and ZFS. So it could very well be a derivative of the previous problems where a more complex situation in storage ended up in deadlock. Thanx to Steven for putting the finger in the correct hole in the dike.... For the time being I'll just pop the sysctl into the config. --WjW
