But the laptop, so far, doesn't expose the problems of crashes described above. The laptop is the only system so far without ZFS! The most frequent crashing box is a CURRENT server with the largest ZFS volume. When on most recent CURRENT (>r307157, see above), starting a scrubbing on a RAIDZ volume with ~ 12 TB brutto size AND running a poudriere job, triggers the crash every 1 - 18 minutes. Another box with only /home as ZFS volume on a dedicated hdd crashes after minutes or hours. A laptop, also CURRENT (now at r307349) without ZFS is working stable as long as I do not pull the LAN wire (a problem I described also in the list, I try to capture the screen when crashing right now).
