Thanks Johannes very much for collecting the log.

The root cause should be the following:

	- if 'offset' of one segment isn't zero, we can't make that segment
	  at full size, otherwise the segment ends in the unaligned
	  virt boundary.

Give me a while, I will figure out one patch to address the issue.


Thanks,
Ming
