A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed.

this issue is related to X11, and [possibly] to X11-i810/intel driver and intelfb This did occur with xorg-server-X11-Xorg 1.0.8 I'm using xorg-server-X11-Xorg 1.1.1-xxx from AIGLX fedora repo, where this issue does not happen. Please don't close this bug. I will upgrade to 2.6.18, downgrade X11 and report back in a few days. Thanks for update, Konstantin
this bug does not present on FC6 2.6.18-1.2849 and 2.6.18-1.2798 kernels. No issues with either suspend/resume nor switching to a text console. Perhaps this bug can be closed. Rgds, Konstantin
