Description Charlotte Richardson 2008-04-30 16:35:50 EDT
Description of problem:
Two things:
1) /sbin/mkdumprd does not actually have --with-module, which presumably would
do what the extra_modules line in /etc/kdump.conf does. The only way to get
extra modules loaded by the kdump kernel is via /etc/kdump.conf.
2) /etc/kdump.conf does not expose an interface to /sbin/mkdumprd's --preload
<module> function, which would be extremely useful for us. It works fine if you
run /sbin/mkdumprd directly, and has the desired effect (the module loads before
the SCSI modules load).

Version-Release number of selected component (if applicable):
RHEL5.2 kernel build 89.

How reproducible:

Steps to Reproduce:
Try /sbin/mkdumprd --with-module and --preload.
Actual results:
--with-module is not available. --preload works, but not from /etc/kdump.conf.

Expected results:
Would be really useful if both of these worked in both places.

Comment 3 Kevin Krafthefer 2008-05-22 12:09:29 EDT
This RFE has been reviewed during the RHEL RFE review
with Red Hat product management. This request has been *tentatively* approved
for inclusion
in the next update. This decision is not final and still pends further
technical review and scoping by Red Hat development engineering.
Comment 4 Neil Horman 2008-05-23 14:33:38 EDT
I've removed the --with-module option in 1.102pre-22.el5.  Note that the
extra_mods option in /etc/kdump.conf should provide you with the additional
functionality that --preload would otherwise provide.
