Hi Linus et. all
While under massive disk and cpu load, 2.4.0-prerelease produced the following oops (decode see below)
Keith, I've read the FAQ about having been bitten by Makefile bugs with certain symbols and such, yet I still get these symbol warnings even after a mrproper rebuild. Any clues?
-Udo.
