I found out that this is not only nvidia and i865 related. Several intel chipsets suffers from this issue, and using ATI boards makes the problem appears as well. This makes the bug's relevance critical.
i945 shows the very same problem (which makes this one not being a specific isolated case). Edgy daily builds has this issue as well, which makes this bug not being 2.6.15 related only. -- panic/lock/restart on dapper-amd64 if there's intel integrated video AND a nvidia card at the same time https://launchpad.net/bugs/55104 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
