vmcore-dmesg exits with "No program header covering vaddr"

[Prasad Koya]

Hi

In my 64bit, 3.4 kernel, I'm increasing dmesg buffer size at runtime
by passing log_buf_len=512K at command line. At compile time, I have
LOG_BUF_LEN as
256K. However, when this kernel crashes (crashkernel set at 64M),
vmcore-dmesg fails with below error. I tried with both
kexec-tools-2.0.4 and 2.0.6.

No program header covering vaddr 0xffff88013ff00000found kexec bug?


Thank you.
