During some testing, my qmeu kernel hangs. Any way to create core dump for this hung kernel? Linux ways of alt+sysrq is not working!
You can use the qemu backend to query the kernel and debug. http://wiki.qemu.org/download/qemu-doc.html#pcsys_005fkeys Boot with 'nographic' and you should have full access. Cheers, Bruce

The qemu which I am using has got kernel as 3.2.11. How can I upgrade it to kernel 3.4? Any other way than compiling from the yocto source?

Where can I get those? I visited http://downloads.yoctoproject.__org/releases/yocto/ <http://downloads.yoctoproject.org/releases/yocto/>. but could not figure out the headers! Kernel on my qemu (x86) is 3.2.11-yocto-standard The kernel headers are simply the mainline kernel sources, with "make headers_install" executed, packaged and placed in the sysroot for the build. So just look in your build/downloads/ and you'll see linux-3.2*tar.bz2, those are your kernel headers source. Cheers, Bruce Kindly assist is getting the headers.
