Package: xen-linux-system-2.6.26-2-xen-amd64
Severity: important
Hello,
Yesterday we had a domU PV host freeze up in a file location. The following log
was received:

This domU could not be rebooted, and had to be xm destroy then recreated again
before the filesystem was accessible again. This machine has been running
successfully for over 6 months before this issue occurred, and we run a number
of other 2.6.26-2-xen machines that have not had this issue (fingers crossed!).
If there is any explanation of this, how to avoid, or if it has been fixed in a
newer kernel, this would be ideal.
Thanks

Thanks for reporting it, and sorry for the slow response.
Did this only happen once, or was it reproducible? If it happened
again, on which kernel?
Sincerely,
Jonathan
