This is on a Thinkpad Z61m running amd64. Suspend on lid closure has worked without problems for many months with numerous snapshots. After upgrading on 30 April the machine no longer wakes on lid opening. The sleep symbol below the screen blinks repeatedly but nothing else happens.
If I suspend it with Fn+F4 the same thing happens; it is impossible to wake the machine. Another Thinkpad running i386 is not affected.
