This probably doesn't have much to do with md, it is a generic Linux kernel failure in the VM subsystem. If the search on bugzilla.kernel.org was up, I'd point you to bug numbers (there was quite a lot of reports), but it isn't, so just see: http://www.google.com/search?ie=UTF-8&q=page+allocation+failure https://bugzilla.redhat.com/buglist.cgi?quicksearch=page+allocation+failure e.g.: "they are happening during heavy network and disk activity when the system has plenty of memory free" https://bugzilla.redhat.com/show_bug.cgi?id=551937 and: "This is very common. e1000 attempts to do large memory allocations from within interrupt context and the page allocator cannot satisfy the allocation and is not allowed to do the necessary work to make the allocation attempt succeed. It's the same with all net drivers" http://kerneltrap.org/mailarchive/linux-netdev/2009/4/13/5473414 In your backtrace I see the system was also handling a network transfer with the r8169 driver; do you use jumbo frames there (MTU over 1500)? -- With respect, Roman ~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Stallman had a printer, with code he could not see.
