Event posted on 02-03-2010 03:20am EST by arindam.nath File uploaded: fix_khungtaskd_cannot_freeze_during_S4.patch This event sent from IssueTracker by jkachuck issue 463493 it_file 358903 Event posted on 02-03-2010 03:20am EST by arindam.nath The attached patch fixes this issue. Root Cause: When system prepares to enter S3 (or S4), it tries to freeze all user processes and kernel threads. It sets the PF_FREEZE flag in the struct task_struct before sending a wake up signal to the kernel thread. The kernel thread should in-turn check the value of this flag after being woken up to confirm whether it is a request to freeze and take appropriate action.
