Hi,
I'm running FC18 with KDE on a Dell Inspiron Laptop on which hibernation doesn't always work.
Sometimes it hibernates as it should, but most of the times the screen turns black and after a few seconds the fan stops spinning but the device doesn't power off, it just freezes. Only a reboot by holding down the power button gets it back. It seems as if no hibernation data is written to SWAP (which should be large enough - 11GB/8GB RAM) before the freeze, as the inidcator light doesn't do anything.
Trying to figure out what might be blocking hibernation tried to unplug all USB devices, tried to unload USB kernel modules before hibernation, disabled networking, wireless etc but nothing worked. Unfortunately it doesn't write any logs. The only thing messages states is this:
After that - nothing, only the next reboot.
This is what it displays before a successful hibernate:
According to lspci Device 00:07 is my network adapter. But no idea why he talks about resuming here when he is just going to hibernate?
Any ideas how one can debug this problem and why it sometimes works and sometimes not?
Suspend to RAM works flawlessly.
