Also, there were several differences in the output of `sudo lspci -vvnn` between the good and the bad sessions. For several of the devices, there seems to be a consistent change in the MAbort flag between the good and bad session, although PresDet switched for the Root Port, the Audio Controller had a different data value on line 104, and the SATA controller's address changed. However, there are several different and missing values for the GPU (starting at line 457). After the GPU though, there are a couple switched flags for the Wireless Network system (and MAbort isn't one of them), but nothing else.
