Forgot to mention that the trouble starts with start of kernel, right after boot. And it affect not only Ubuntu. This bug was once fixed in 2.6 kernels and it worked up to 2.6.39.3, but then was a regression. Here's old patch, maybe it will be helpful: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e44718318004a5618d1dfe2d080e2862532d8e5f
