Got exactly the same, from at least 2.3.51 up to -pre6.6 (didn't try more
recent kernels), when using a huge memory hog (pnmcrop on a 28 Mb .pnm
file, ate ~150 Mb RAM (96 physical), then died, same oops, same line.
Already reported, was ignored/overseen). 2.4.0 can't ship with that !
It seems it's related to the interactions between SHM and swap.
