Hi, Cijoml
    Will you please attach the output of dmesg after the system is resumed from hibernation?
    From the log it seems that the interrupt is enabled while calling the function of sysdev_resume.
    Maybe the irq is already enabled while the system is resumed from the hibernation swap partition.
    Thanks.

dmesg-2.6.30

There is also tracelog during suspend, but it is so quick, that I can't catch it and after resume it is not in dmesg.

Comment 6 ykzhao 2009-07-21 08:12:50 UTC
Hi, Cijoml
    Will you please try the debug patch and see whether the issue still exists in course of resume from hibernation?
    Thanks.
Comment 7 ykzhao 2009-09-11 02:48:14 UTC
Since there is no response for more than one month, the bug will be rejected.

If the problem still exists, please try the debug patch in comment #5 and attach the output of dmesg.

Thanks.
Comment 8 Cijoml Cijomlovic Cijomlov 2009-09-11 16:31:35 UTC
Hi there Problem is still in 2.6.30.5. I will attach dmesg log soon. Sorry for not replying for a long time!
Comment 9 Zhang Rui 2009-12-28 08:18:02 UTC
please re-open it and attach the test result if the problem still exists in 2.6.32.
