I doubt the debuginfo package install has anything to do with it, as
that is really only used by things like crash (and maybe perf?).
Enabling kdump does cause some changes though, as the kernel will
reserve a section of memory to put the kdump kernel in. It's
plausible that your machine is tripping on some memory issues and
enabling kdump is forcing the kernel to not touch that memory at
runtime. It's something of a long shot but it's plausible.
I am going to try the memtest. The system this morning was incredibly
sluggish with a yum install taking several times longer than in the
past. A reboot of the system this morning had it oops a lot on agetty
versus working.. but it locked up solid so a power reboot was needed
so I couldn't get anything 'saved' from ram. sigh.
Will run memtest86 for the day and see if that gets anything. I had
tested the system earlier on my rawhide experience with the IBM
maintenance tools but they may miss something.
If you haven't already, try running memtest86+ for a while and
see if
it comes back with any errors.
