This is something very specific.  E.g., you would not be able to reproduce
the problem easily with tail -F and forced unmount of the volume.  Anyway,
if gamin works and stops normally with the patch, I will just commit it.

RE: ipv6_addrs_IF aliases in rc.conf(5)

2013-07-16 Thread Dewayne Geraghty 
Sato-san,

You have provided a very useful summary of ifconfig parameters for rc.conf. 
However, you are missing one example that would provide
clearer understanding.  Would you please advise if 
 
ipv4_addr_em0="10.2.1.1-10/32"

is deprecated, backward compatible or remains valid into the future?

I particularly appreciate the succinctness of:
ifconfig_em0_aliases="inet 10.3.3.201-204/24 inet6 2001:db8:210-213::1/64 inet 
10.1.1.1/24"

Kind regards, Dewayne.

Hello,

I will run few "poudriere bulk" tomorrow and report the result here.  

I've tried on my workstation at work which uses the same configuration

   Hi,

   I think that's a good point.

   In our company, it�s not allowed to use the stable tree for any
   production system. Little and useful patches are still allowed.

   Having a central point with a description of each patch it would be
   much easier to update the release version with the needed patches.

   Perhaps, each patch could also have a comment section and a state
   (experimental, almost stable, stable ...) or a counter for successfully
   and unsuccessfully deployments.

   Any objections?

   Regards,
   Pascal

I'm not totally clear on this yet -- the entire concept of being able
to do *ranges* is deprecated? Or is it deprecated because it's missing
the CIDR?

Is there a possibility that a separate unofficial  patch set could be
released for people who want  the autotuning but do not want to run 9
stable after 9.2 is released.
I would like the autotuning, but i am a  little reluctent to use other
stable stuff i will get when tracking stable.

Johan

Re: Interpreting MCA error output

2013-07-16 Thread Kurt Jaeger 
Hi!

Approx. two years ago there was a thread on -stable about MCA output.

See

http://lists.freebsd.org/pipermail/freebsd-stable/2011-October/064083.html

for a post from Jeremy Chadwick with a link to a AMD paper on
that topic ?

http://www.amd.com/us/Documents/47644A_ecc_embedded.pdf

which is no longer available 8-( Anyone has a copy ?

There's new mcelog source (1.0pre3), but the MASTER_SITES look deserted 8-(
And I'm not sure the CPU is really supported by that mcelog version,
due to the error:

mcelog: Unsupported new Family 6 Model 2d CPU: only decoding architectural 
errors

We have a HP360 gen8 running FreeBSD 9.1 and try to get support
from HP on that topic.

I'm using ipv4_addrs_em0 now (and ipv6_addrs_em0 with Kimmo Paasiala's
patch), but Hiroki Sato wrote:

hr># IPv4 address range spec.  Now deprecated.
hr>ipv4_addr_em0="10.2.1.1-10"

So I'm a little confused now :) If I'd use post r252015 system then
would this be better way?

ipv4_addrs_em0="10.0.0.66-78/28"

ipv6 syntax depends on if you're using 8.x or 9.1-RELEASE, but you're
going to have to do all the aliases manually.
