Bug#345227: kernel-image-2.6.8-2-686: USB driver ehci_hcd fails to enter ACPI S3 state on IBM Thinkpad T40
Subject: kernel-image-2.6.8-2-686: USB driver ehci_hcd fails to enter ACPI S3 state on IBM Thinkpad T40
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-16sarge1
Severity: normal
*** Please type your report below this line ***
When running ACPI, attempting to enter S3 sleep state is not successful
presumably because of the USB driver and the laptop immediately goes back to
normal operation. When the ehci_hcd module is not present, system enters
sleep state with no issues but USB2.0 is not available. System will also
wake up with no issues.
S3 state is entered by "echo 3 > /proc/acpi/sleep"
