Hello Konrad,

I follow your suggestion and I downgrade the Xen dom0 and hipervisor to
the 3.1.2 vesion and 2.6.18-194.3.1.el5xen kernel (versions by default
in RHEL 3.5).

At this moment all works fine, but this message in /var/log/mesages
worry me a lot:

pciback 0000:09:00.0: Driver tried to write to a read-only configuration
space field at offset 0x4c, size 2. This may be harmless, but if you
have problems with your device:
1) see permissive attribute in sysfs
2) report problems to the xen-devel mailing list along with details of
your device obtained from lspci.

This is the same message that appears in the previous update to xen
3.4.1 that I did make, and at the moment to make it, all works fine
also.
Then, after a lot of network traffic, the system began to freeze, as I
describe in my first message.

The question is if I add the address in the message in the
xend-pci-permissive file can solve this, or if I need to downgrade to
lower version to avoid it.


Thanks for you answers.

Paco.
