NOTE TO PEOPLE WHO THINK THAT FreeBSD 8.x IS SLOW ON IA64 OR SUN4V:
For ia64 the INVARIANTS and INVARIANT_SUPPORT kernel options
were left in the GENERIC kernel because the kernel does not
work properly without them. For sun4v all of the normal kernel
debugging tools present in HEAD were left in place because
sun4v support still needs work to become production ready.
New version of minidump format for amd64 architecture was
introduced in r215872. To analyze vmcore files produced by
kernels at or after this version you will need updated userland,
libkvm actually, that is able to handle the new version.
A workaround for a fixed ld bug has been removed in kernel code,
so make sure that your system ld is built from sources after
revision 211583 from 2010-08-21 (r210245 from 2010-07-19 if
building stable/8 kernel on head, r211584 from 2010-08-21 for
stable/7). A symptom of incorrect ld version is
different addresses for set_pcpu section and __start_set_pcpu
symbol in kernel and/or modules.
A new version of ZFS (version 15) has been merged.
This version uses a python library for the following subcommands:
zfs allow, zfs unallow, zfs groupspace, zfs userspace.
For full functionality of these commands the following port must
be installed: sysutils/py-zfs
