I didn't have any crashes but abrt kept thowing SELinux errors on fc 12
with 2.6.33-1.rt kernel. I similarly removed the complete abrt suite and
haven't had any problems since...

>>> Most of the time when I was seeing very strange problems on this machine; usually typing "dmesg" on a term was enough to get the kernel dump. I'd scroll up from the bottom and copy over everything from just above the kernel dump. Also, there was always "/var/log/messages" to look at.
>>> I'm not sure what Fernando thinks about it, but I'm all for posting bug reports for the ccrma-rt-kernels here on the list. I'm sure that the stuff that matters will get forwarded to the right people.
>>> Just try to remember that the kernel folks don't look into problems with kernels that are running proprietary drivers, so if your dump says it's "tainted" instead of "non-tainted", you are on your own!
>>> BTW, on this machine I could never turn in a bug report because it was tainted with the "nvidia" driver. I had to run the machine with the driver because it was an "sli" card and the nouveau and nv driver would not work with it. I finally went and replaced it with a newer, but less power hungry :) nvidia card that works with the nouveau driver.
>>> When I was having crashes it took forever to find what was wrong, and this with a stock fedora 26.32.xx kernel. Every crash would point to something else. I eventually found the problem after turning off all of the daemons I could, and testing, and turning stuff back on until I found that the "cpuspeed" service cannot be used on this machine. In my case I think it may be because I'm using an early dual core amd64.
