[Crash-utility] "crash: cannot allocate any more memory!" for 2.6.27.4

[Dheeraj Sangamkar]

Hi,
I am able to use crash to debug a crash dump generated when I initiate the
crash using the sysrq-trigger in the /proc directory.
But when I try to use crash to debug a kernel vmcore generated due to the
insertion of my module, I get the error below.

Please let me know if I am doing anything wrong or if you think that the
dump is corrupted. I use kdump for dump collection.
I am using a 2.6.27.4-2-default kernel.
