Does that mean anything?

There was apparently an error (possibly a bug in the kernel code). While unsettling, if your system kept running, it probably doesn't mean anything. It's just something that you don't want to see every day (if you do, it might be a good time to upgrade your kernel  ) |

It seems to be happening at regular intervals...
22:16:48
22:22:03
22:36:13
22:43:53
22:50:58
seems to correspond to when my screen saver kicks in...
I dont notice any bad behavior, system seems stable... Monitor doesnt shut off like it used to when using WinXP...
running 2.6.5 gentoo r1 kernel

What about this? In the ck4 kernel (and other 2.6.x's, too) when thjis message showed up i always noticed an application crash and after a few minutes the system hangs... Maybe it's not serious (in ck5 i've got slightly different kernel conf. & it works), but it seemes there's still a bug in page_alloc.
