Hi All, i'm running Fedora core 6 on a power book G4. I'm running the latest kernel. I noticed problems after going to sleep/wakeup ( i've had applications stuck waiting on futexes , weird behaviours that disappeard after a reboot, implying badly messed up kernel structures ). I've got the following logs in /var/log/messages yesterday after going to sleep for the first time after upgrading to the latest kernel ( Linux kaluha 2.6.18-1.2849.fc6 #1 Fri Nov 10 12:40:25 EST 2006 ppc ppc ppc GNU/Linux ) From the logs i understand that the following is happening: i'm closing the lid; pmud tries to put the system to sleep then comes the BUG, It somehow causes a waekup of the video card , network card , hard drive etc ... but then another crash :( then nothing ( sleep with all devices enabled ? ), until the wakeup this morning .... This sounds pretty messed up . Is anyone else experimenting these problems ?

Here's the log in /var/log/messages:
