hi all,
      I have just ported the pvovhvm drivers to ubuntu 10.10 ,the domU can boot successfully, but when the domU running,  intermittence�� the system will give me such warnings:
      INFO: task login:1073 blocked for more than 120 seconds.
      "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disa bles this message.
      INFO: task flush-202:0:457 blocked for more than 120seconds.
      "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
      INFO: task jbd2/sda1-8:422 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
      what's wrong with the domU? is it means there are some errors in
xen-blkfront? how should I debug this error???
      Thanks a lot.
