If my following of one of the kernel threads is correct, this is a serious
kernel bug that occures when you either have a heavily loaded system or a
very low memory system. The trouble is that the kernel has allocated all
your memory to the disk cache (or other things) and desperately requires a
new empty page to continue functioning. It cannot free any in memory pages
for some reason (Dirty?)
I saw a post where someone mentioned that he could reproduce this by
compiling two kernels at once and doing some other operations.. Donno..
What you two are reporting might even be something completely different.
