Any comment to this ?

Last time it took 26 minutes (running top with 0.5 seconds update in
parallel). Last active process was xend.
This time only 1½ minutes:

Intrestingly in my previous test the "xend" refused to start and the system
did not crash for 1 hour and 20 minutes. Then I rebooted, because the "xend" was
not running. The "xend" gave the following error message:
File "usr/lib/python2.5/site-packages/xen/util/pci.py", line 1226, in
find_capability
('Looped capability chain: %s' % self.name))
PciDeviceParseError: Looped capability chain: 0000:07:00.0
[2010-09-08 14:28:26 6885] INFO (SrvDaemon:220) Xend exited with status 1.
This seems to be caused by wrong PCI data (or initialization). An "lspci" gave
the following:
07:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection (rev ff)
08:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection (rev ff)
The revision of 'ff' is bogus. The pci config data presented in /sys or /proc
was
only "ff,ff,...", hence the wrong revision.
I had to switch of the hardware to normalize this.
After this the "xend" was starting and the system crashed...
