Red Hat Bugzilla – Bug 811044
ehci_hcd and xhci_hcd shouldn't be built into the kernel
Last modified: 2012-09-05 09:42:46 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.
Steps to Reproduce:
1.use the fedora kernel
2.suspend to ram
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.
Closing this out per Dave's comment. If you're seeing crashes or issues, please report those in separate bugs.
