I occasionally encounter this and was also thinking I must have some edge case hardware glitch since I haven't heard anyone else talk about it. In my case, I wouldn't say it's completely random - there's always something I do that is graphics related that causes the freeze. It's never something repeatable, but it is always something related to the contents of the screen being updated. I think that's what you are describing as well.
I've not reported it before because it is so random and difficult to debug. I do software development professionally and know how hard it is to help someone with a problem that can't be intentionally reproduced. I'm using SHR-T. The image is dated March 3rd, 2010. I downloaded it and the "latest" kernel image at the same time on March 10th. It is kernel version 2.6.29-rc3. This is the most stable image I have run yet. I tried doing some upgrades at one point, but had more issues; so I reflashed the image. With this image, I'm probably down to only having this type of freeze maybe once every 2 weeks or so. I've never tried fbdev. If anyone of the devs have some suggestions as to how to try to debug this, I'd be happy to try. Maybe a script that periodically gathers and saves some data that can be reviewed after rebooting?
