Description Nathan 2012-04-10 00:16:08 UTC

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:
Crash

Expected results:
Suspend to ram

Comment 1 Dave Jones 2012-04-11 17:19:28 UTC

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.

Closing this out per Dave's comment.  If you're seeing crashes or issues, please report those in separate bugs.
