@ Daniel Richard G.
I performed following steps to resolve the crashdump hang issue.
[Issue 1]default crashkernel=... Changed the crashkernel to use 128M instead of 64M in /etc/grub.d/10_linux. dmesg displays 128M reservation as expected.
[Issue 2] makedumpfile throws "error while loading shared libraries: libdw.so.1 cp /usr/bin/makedumpfile /root/makedumpfile_org cp /bin/makedumpfile-static /usr/bin/makedumpfile
Even now the system is unable to generate core file. It's hung. Please let me know if I missed any step.
