double speed issue with xen-unstable

double speed issue with xen-unstable

[Christian Leber]

Hello,

I did a fresh hg pull this morning (10:30 CEST) and installed it and
until now I did not see this reported on the list:

sleep 10

only takes only 5 sec in realtime, that happens in dom0 and domU.

(Environment: Debian sarge on i386
 Hardware: AthlonXP 1800, 512 MB)
(with Xen 2.0.6 this doesn't happen)

Works fine for me on a couple of different machines. It would be good if
other unstable tree users tried this, and perhaps we can spot a pattern.
Having the xen/dom0 boot messages may be useful too.

Now i have another pattern... because sometimes when i run
/etc/init.d/xend networking stops working completly i tried several
times.... and now booting took allready very long.

And sleep 10 takes forever, I stopped it after 20 MINUTES.
xm dmesg is here, but it doubt it helps:

Oh, the ifconfig output when the networking fails looks like this:
http://debian.christian-leber.de/ifco.works
otherwise like this:
http://debian.christian-leber.de/ifco

the software is of course completly unchanged, sometimes it works,
sometimes not.
