Thanks for the conformation on this, well I have tried to solve this issue, but failed. >From my understanding it's like IRQ locks that are being hold up by the pl330 dma module. But this module also have related to serial driver. So I got but stuck up. Well I will keep on trying, If I have some thing I will share that. -Anand Moon >> >> [ 139.806823] ========================================================= >> [ 139.811934] [ INFO: possible irq lock
