Re: Sleep/resume problem on s3c2440

Do you acknowledge your interrupt when it fires? Make sure your interrupt
can fire again before entering suspend mode.

Hi All,
I am facing a strange problem. I can suspend and then resume by activating
wakeup interrupt first time, but when I try to suspend/resume second time
,
the system hangs. Can any one help in this situation? I think the system
can't restore some thing important during first resume. Is it correct?
An early response will be highly appreciated.
Many thanks in advance.
Sohail Tariq
