So is it ehci that causes problems, e1000e, or is combination of both needed?
In init=/bin/bash, as soon as e1000e gets loaded, the system wakes up. Unloading ehci_hcd just seems to workaround the issue.
Can you try vanilla kernel (maybe KOTD?)?
See comment #7. In the meanwhile, I also tried 2.6.26-rc8, same behaviour. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
