Additional test:
Change crashkernel=192M in 4.17 kernel, everything looks well.

Comment 2 Qiao Zhao 2018-06-05 10:12:33 UTC
The following results are my test by rd.memdebug=4 in /etc/sysconfig/kdump.

Comment 3 Qiao Zhao 2018-06-06 06:05:24 UTC
Retest by latest kernel kernel-4.17.0-1.fc29, crashkernel=160M works well both local and nfs dump. So, we can close this bug as NOTABUG.

Comment 4 Jan Kurik 2018-08-14 10:29:53 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.

Comment 5 Dave Young 2019-10-28 09:13:39 UTC
It should be not a bug, please increase the crashkernel memory size for kdump to work
