<div dir="ltr">Hi Vipul,<div><br></div><div>Although you havent provided any technical info regarding your hand issue </div><div>But anyways I would sugegst you to perform very basic debugging techniques:</div><div>1) raise the kernel log level to highest "echo 8 > /proc/sys/kernel/printk"</div>
<div>2) try to reproduce it and narrowdown your issue to a perticular scenario at which this hang happens or it happens randomly.</div><div>3) Then try to log inside user code that is responsible in that perticular scenario and then post your exact execution code point of problem.</div>
<div>Otherwise it is hard to say where the issue lies and it will just be bluffing nothing else.</div><div><br></div><div>Regards </div><div>Sanjay</div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">
