I had strange problem last night, while browsing this site.
I was checking the forum and specially this thread and the browser got hanged and my N900 rebooted automatically. I thought something might has stuck, so after bounce, opened this thread again and while trying to scroll the screen via finger, it hanged again and rebooted.

Not once, not twice, it did the same reboot three times. Since then, I have not opened this site from my N900 browser. But I, I check any other sites and it works fine.

Looks pretty weird . huh.
