2.6.1: kernel BUG at mm/swapfile.c:806

From: marcel cotta
Date: Thu Jan 15 2004 - 21:53:53 EST

hi

i got this oops after the box swapped like crazy under X for about 5 minutes
while swapping it was nearly unusable (jerky mouse, console switching took 10 seconds)
the extreme performance drop is always reproducible when swapping starts
