Hi Brian et al, First, can you try booting the latest 3.2.0-22.35 kernel. I just want to confirm this isn't resolved before we investigate further.
Assuming the issue remains, lets try and figure out the exact change which introduced this regression. Between the 3.2.0-17 and 3.2.0-18 kernels there were quite a few changes, most notably rebases to upstream stable Linux kernel v3.2.7, v3.2.8, and v3.2.9. 3.2.0-17.27 was actually based on upstream stable Linux kernel v3.2.6. So lets have you do the following set of tests: 1) Install and boot the upstream v3.2.6 kernel. Does it work (ie boot properly) or panic? If it works, proceed to step 2. Note that I would expect this kernel to work, but want confirmation. 2) Install and boot the upstream v3.2.7 kernel. Does it work (ie boot properly) or panic? If it works, proceed to step 3. 3) Install and boot the upstream v3.2.8 kernel. Does it work (ie boot properly) or panic? If it works, proceed to step 4 4) Install and boot the upstream v3.2.9 kernel. Does it work or panic? Let me know your results of the above.
