Same here. I can provoke an instant panic running (for example) a make
buildworld and
bonnie++. I have all the filesystems on ZFS, booting from a USB
pendrive. I tried to set
the kernel memory limits to 1.5 GB but it still crashes with the
kmem_too_small panic. I also
tried the patch supplied by Pawel.
The machine has 6 hard disks configured as a raidz2 pool.
Please let me know of any test anyone might need.
Borja.
