[Xen-users] Problems with HVM S3

[Mathias Gottschlag <mathias.gottschlag@xxxxxxxxxxxxxxx>]

Hello,

I am currently trying to suspend a HVM domU via ACPI. However, after "xl 
trigger vm s3suspend" the virtual machine freezes after 2-3 seconds (I get a 
prompt at xl console before that!), and keeps printing the following lines:

[  240.428145] INFO: task jbd2/xvda1-8:146 blocked for more than 120 seconds.
[  240.437649] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables 
this message.
[  240.448222] INFO: task flush-202:0:1886 blocked for more than 120 seconds.
[  240.457373] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables 
this message.

I am running a xen build from hg one or two weeks ago, and 3.4.4 linux on dom0 
and domU (I also tried linux 3.2 on domU, no change).

I attached the vm configuration, is there any documentation on how ACPI S3 is 
supposed to work? Can anybody explain those error messages, or tell me how to 
debug the problem?

Best regards,

Mathias Gottschlag
