Pkg xen devel - Dec 2012 - Bug#631102: #631102 and #679533.. related?

Kevin,

Would you mind taking a look at #679533
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679533) and give some
feedback about how similar this issue is to your report in #631102 here?

There was a hint 631102 might be similar, but from the text in this bug
report it's not clear to me if this is about the same issue. Maybe you
could comment on it.

First results of a big shoot-out session (reproducing and isolating the
bug) last week is that we found out disabling hyperthreading in the
server bios made our issue go away. Knowing that... we now see, looking
back, that after we switched on HT together with the lenny->squeeze (xen
3->4) upgrade, this issues started to pop up weeks later in production.
The obscure bug did not bite during upgrade-testing. :|

Thanks,

I skimmed through this but cannot say.  I no longer have access to the
hardware.  My solution was to switch the entire company to kvm.

Ok.

Haha :-)

You might consider closing the bug report although, if the issue is not
relevant any more.

Bug 631102 I suggest closing as cannot reproduce if it has not been seen in
the wild.  I do not have access to the hardware anymore.
