I'm not really that much of a newby (2 years of linux) but I am a newby to
kernel dumps.
I'm running Redhat 7 with the latest kernel compiled using kgcc. I get many
many oops, lockups and mysterious reboots. Can anybody help me determine what
is causing this from ksymoops output below. I thought it might be something
with my swapper file so I deleted and recreated the partition. I still have
the same problem. This system was rock solid under 6.2 but is pretty much
useless now. This is pnly the last couple of Oops after a reboot. I have
dozens in my messages file. :(
