BUG: scheduling while atomic: dslmgmt/53â8/0x000002â01

Hi,
I see this error message intermittently. As per other post on similar
issue, this happens when schedule is called from either interrupt
context or some other atomic operation (Might be after acquiring
spinlock).
But from the call trace am not getting any clue, please help me guide
on this issue.
