Thanks for the great work!

I have a amd64 box with 8GB RAM running CURRENT-200806 snapshot. I get
the latest version of the sources with csup, applied your patch and
build the world/kernel.
/usr/src and /usr/obj are located on a zfs file system. After "make
installkernel" and reboot into single user mode I had to start the zfs
file system but it failed:

# fsck
# mount -a
# /etc/rc.d/hostid start
Setting hostuuid: ...
Setting hostid: ...
# /etc/rc.d/zfs start

WARNING: ZFS is considered to be an experimental feature in FreeBSD.
ZFS filesystem version 11
ZFS storage pool version 11
internal error: out of memory
internal error: out of memory
internal error: out of memory
internal error: out of memory

Running "zpool list" shows no available pool and the "internal error:
out of memory" error message.

The same problem occurs in multi-user mode. loader.conf is set to:
vm.kmem_size_max="2147483648"
vm.kmem_size="2147483648"

Increase/remove the kmem_size-values didn't change anything.

To solve the problem I had to boot kernel.old and run make
installworld/mergemaster. After rebooting with the new kernel the pool
was available again and everything work without a problem.

Did I do something wrong when I upgraded the server?

Beat
