Public bug reported: I have lots of page allocation failures in my Ubuntu 12.04 on Toshiba AC100.
Perhaps, we should change the default for/proc/sys/vm/min_free_kbytes -- as suggested in https://bugs.launchpad.net/ubuntu/+source/linux- ac100/+bug/1035208/comments/16 by marvin24 . What it is now set to: ~ $ sudo cat /proc/sys/vm/min_free_kbytes 2698 How many failures I get: ~ $ sudo cat /var/log/kern.log | fgrep failure | wc --lines 99 I'm afraid it is bad for the system's stability. I'll try to put vm.min_free_kbytes = 4096 into /etc/sysctl.d/99-min-free-mem , and see whether they disappear. Of course, this might not be very good from the other side: this computer has little RAM: ~ $ free -m total used free shared buffers cached Mem: 435 303 132 0 0 15 -/+ buffers/cache: 287 148 Swap: 976 304 672 ~ $ , and this setting might cause it to swap in more cases, and cause more resource consumption (CPU and I/O)...
