I was able to reproduce this same issue on bare metal HP BL460G7 server. After
applying the attached patch the issue appears resolved. I verified I was able
to load and then boot into the new kernel with kexec -e as well as successfully
collect a core dump after executing sysrq-c.
Thanks,
Hello,
I tried to reproduce the issue in a i386 qemu VM and think I found something.
Function is_crashkernel_mem_reserved tries to search for the start
and end of the crashkernel reserved memory area.
This is done by calling kexec_iomem_for_each_line and given a callback
function as parameter.
Package: kexec-tools
Version: 1:2.0.7-5
Severity: grave
File: /sbin/kexec
Justification: renders package unusable
Dear Maintainer,
When running kdump-config on an i386 VM configured with 2048M
of memory and crashkernel=256M, kexec is unable to load the
kdump kernel and exit with the following
3 matches
