Comment 137 for bug 1419355

My understanding is that the XHCI_SPURIOUS_WAKEUP and XHCI_SPURIOUS_REBOOT flags are tightly related: in the history of these two flags which I linked in my commit message, one can see that applying one of these flag seems to fix a bug but introduces a new one which is fixed by applying the other flag.

As I tried to highlight in the commit message, these two flags seem not to have been applied at the same time for machines having non-LP LynxPoint controllers except for HP machines between commit c09ec25d3684cad74d851c0f028a495999591279 ("xhci: Switch Intel Lynx Point ports to EHCI on shutdown.") and commit 0a939993bff117d3657108ca13b011fc0378aedb ("xhci: Switch only Intel Lynx Point-LP ports to EHCI on shutdown.").

From the comments along this bug report, it seems that applying these two flags seems to fix the problems for machines having non-LP LynxPoint controllers, at least for certain vendors, which we confirm for HP machines.

Feel free to ask us if you need help in testing. We will be glad to help you (to the extent that we have the availability to do so).
