[Xen-devel] some errors of pvonhvm : xen-blkfront

[topperxin <topperxin@xxxxxxx>]

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" disables 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.
