Some times, during a reboot, the system hangs and the only logs on console are <br />
CPU#0 stuck for 67s! [migration/0:5]<br />
The time for cpu being stuck is either 67 or 68 seconds. There is no stack trace. A cold boot solves the problem.<br />
<br />
As of now, we have only observed this when we change the kernel to boot from. We have two kernels (both centos 6.3 -- 2.6.32-279.22.1) installed and when we move from one to the other (by modifying grub), the machine hangs itself at the time of boot. This has been observed in multiple systems at random times and all of those are from Dell. <br />
<br />
Similar bugs seem to be reported elsewhere but could not find a solution.
