This is a first attempt to address the problem. As both cases have problems
with that order-6 allocation, lets try to avoid those allocations while the
module is loaded. So the patch I added to the test kernel keeps the largest
requested buffer until the module gets unloaded. The kernels are at
http://people.canonical.com/~smb/bug363150/.
If someone with the problem could try one of these kernels (and make sure you
have not linux-backports-modules installed) and let me know whether this
improves the situation. (Another note, its still a test patch and it prints out
some allocation and free statistics)
** Changed in: linux (Ubuntu)
Status: Triaged => In Progress
