Comment 6 for bug 746137

it seems i spoke too early:

natty: http://pastebin.ubuntu.com/591172/
maverick: http://pastebin.ubuntu.com/591194/

both while doing network activity and with vm.min_free_kbytes = 8192

Marcin reported another trace that looks identical: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/690370/comments/28

He got his while doing a kernel compilation on a usb hdd.

IMO this and lp690370 share the same root problem.
