Description Nathan 2012-04-09 20:16:08 EDT
Description of problem:
ehci_hcd and xhci_hcd are known to cause problems when suspending to ram. Therefore they shouldn't be built into the default kernel, but instead loaded as modules, allowing pm-suspend to suspend them before suspending to ram.

How reproducible:

Steps to Reproduce:
1.use the fedora kernel
2.suspend to ram
Actual results:

Expected results:
Suspend to ram

the real fix is going to be figuring out what needs to change in the usb drivers to correctly handle suspend/resume.

We can't make them modular without breaking things like usb serial console, and other usb devices that are needed in early boot.
