Tried it yesterday on a freshly updated FC-devel box and it worked like a charm
(suspended my monitor nicely... ;) )

Read ya, Phil
Comment 2 Matthias Clasen 2006-02-15 09:53:26 EST
Not good enough, Phil. It does not work on either of our test machines.
One is x86_64, the other i386.
Feel free to visit us in the megacube to check it out
Comment 3 Jeremy Katz 2006-02-28 22:15:15 EST
Matthias -- is this still failing?  I'm not seeing it fail on any of the boxes I
was doing suspend testing on today.
Comment 4 Matthias Clasen 2006-02-28 22:24:39 EST
Not in a position to test it this week.

Ray, can you update the test machines and see if this still occurs ?

Maybe it was just the xen kernel...
Comment 5 Ray Strode [halfline] 2006-02-28 23:17:11 EST
sure i'll try
Comment 6 Matthias Clasen 2006-08-26 01:52:28 EDT
Should probably close this now.
