I think this may be a duplicate of bug #364530. I own a Core 2 Quad 6600, and I think I'm experiencing this issue.
I tried first with a Kubuntu Jaunty + nVidia binary (9800 GT) + ubuntustudio-audio, getting a total freeze after entering the session. If I just 'ifconfig ethX down' before entering the session, it works. If I boot with nosmp, it works. I need to test rmmodding the r8169 driver (RTL8111/8168B rev 02). The -generic kernel works fine (I'm using it daily with no issues). I've also tried a fresh ubuntustudio install with audio presets. I can't say it was up to date because mouse and keyboard freeze before the update ended. The progress bar was still "moving". I'm including the result of 'lspci -v -s <my network device>' with this post. ** Attachment added: "lspci-v.txt" http://launchpadlibrarian.net/26542597/lspci-v.txt -- system freeze when using network with linux-rt on smp amd64 machines https://bugs.launchpad.net/bugs/354816 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
