Comment 77 for bug 330824

I'll note that part of the problem is that it doesn't seem to be trivially reproducible even on Ubuntu Jaunty. I was having lunch with a number of Ubuntu kernel developers at the Linux Foundation Collaboration summit, and I talked to them specifically about this bug --- a number of them indicated to me that they were using ext4, and deleting kernel trees, and building new trees all the time, without a problem, and they were on Jaunty.

That being said, there's clearly a problem here, but exactly what are all the reproduction conditions haven't been found yet, so not everyone is able to reliably reproduce the problem. And so far I'm not hearing much from the Fedora 11 beta --- but maybe there's something unique that Ubuntu is enabling by default that makes this bug much more easy to be tickled on Ubuntu that F11. Argh....

On my side, I still need to figure out why a Ubuntu Jaunty kernel built with my custom "no modules" config causes a black screen lockup when booting on an Ubuntu Intrepid userspace --- or find room to do an install of Ubuntu Jaunty beta and try to reproduce the problem myself. Oh, and I have to get my taxes filed too, and expense reports, and lots of other things related to my day job (which doesn't include ext4; it's been a long time since anyone has paid me to work on ext4 as my day job -- it's something I do in my copious spare time in the evenings or when I have a few spare moments).
