Does this patch help? > > http://lkml.org/lkml/2009/10/16/89 This patch seems to help in some cases. Before applying this patch I was able to trigger alloc failures on different machine by booting kernel with "mem=256MB" and doing: $ gitk on-full-tree & # rmmod e100 ... wait for few MBs in swap # modprobe e100; ifup --force ethX So here this patch helped -- with it, I was unable to trigger page allocation failures (testing was short, tough). However, as I said here[1], I applied both of Mel's patches (including this one) and that didn't help my orginal issue (failures after suspend).
