Jump to: navigation, search


Description: System fails to suspend more than once. This is caused by a kernel bug in the USB subsystem that shipped with kernel 2.6.24. It is resolved in 2.6.26.
Systems Affected: Studio 15n
Impact: After the first suspend, the USB subsystem is hung.
Fix: Unload ehci-hcd before suspending. 

$ echo SUSPEND_MODULES="ehci-hcd" | sudo tee -a /etc/pm/config.d/unload_modules
