While I tried to reproduce and bisect the crashes, I face now a strange
situation. With ~r307318, UEFI booting boxes (one workstation with ZFS, a
laptop, no ZFS) do not fail/crash/reboot anymore. The picture is different for
all non-UEFI systems. They still crash/reboot (two servers, both ZFS, one
workstation, with ZFS) after a while: sometimes minutes, sometimes 2 or more
hours. Those boxes crashes with CURRENT > r307157, even the most recent
r307555, while this seems stable on UEFI booting systems.
