Created attachment 521158 [details] boot messages recorded from serial console Description of problem: Something unexpected seems to happen with loading the nouveau module. This results in the graphics mode not being set and plymouth failing to work. Version-Release number of selected component (if applicable): kernel-3.1.0-0.rc3.git0.0.fc16.i686 kernel-3.1.0-0.rc4.git0.0.fc16.i686 How reproducible: Every boot on this hardware. Steps to Reproduce: 1. Have an ancient Nvidia graphics card installed 2. Install latest kernel packages into Fedora 16 3. Boot Actual results: Backtrace, system stays in text mode, gets stuck with plymouth waiting for something. Expected results: Graphics mode is set and system boots as Fedora usually does. Additional info: With console=ttyS0, the boot does not seem to get stuck. The same backtrace is still visible in the first console messages. All messages resulting from adding console=ttyS0 and booting are attached in the report. Hardware profile of the system where this happens is available at http://smolts.org/show?uuid=pub_b44e67c7-277d-4954-9be6-04aaa27fc934

After updating the kernel to a new release [1], I no longer experience this bug. Thank you, whoever got it fixed :-) [1] https://admin.fedoraproject.org/updates/kernel-3.1.0-0.rc6.git0.0.fc16
