Hi Mulyadi,<br><br>I resolved the file system error and now i am able to boot my machine with 3.4.9 Kernel. But still i am facing issues while setting up KGDB,below is the issues i am facing on both development and test machine:<br>
<br>1) Development machine (This machine have KERNEL to be debugged):<br><br>i have added below arguments in grub.cfg file for KGDB to wait for remote GDB connection establishment:<br><br><b>kgdbwait kgdboc=ttyUSB0,115200</b><br>
<br>Again I booted my machine, and now i am able to see below message on screen but for very few seconds , after that machine starts booting normally.Can we pass some time delay till GDB debugger get connected to the test machine ??<br>
<br><b>waiting for remote connection.........</b><br><br>2) Test Machine (where GDB is running for remote debugging):<br><br>I have copy <b>vmlinux</b> file to test machine and start GDB session by giving following below commands:<br>
<br><b>gdb ./vmlinux (</b>after running this command i m getting below logs)<b><br><br></b><br>GNU gdb (Ubuntu/Linaro 7.2-1ubuntu11) 7.2<br>Copyright (C) 2010 Free Software Foundation, Inc.<br>License GPLv3+: GNU GPL version 3 or later <<a href="http://gnu.org/licenses/gpl.html">http://gnu.org/licenses/gpl.html</a>><br>

</div>hm, since your root fs is ext4, well then I guess that is safe...<br>
<br>
> CONFIG_EXT4_USE_FOR_EXT2 3=Y<br>
<br>
not sure what this variable does. Are you sure it is safe?<br>
<br>
anyway, are you sure that the ext4 support itself is already enabled?<br>
either as built in (=Y) or module (=m). If you choose to make it as<br>
module, don't forget to rebuild the initrd/initramfs. Usually "make<br>
install" in the kernel source tree will take care of that.<br>

<br>
</div>not sure what to say here...but I guess that warning is normal because<br>
ext4 is not really backward compatible to ext3/2<br>
