Hi,
I'm using F13 x86_64 on a Dell Vostro 1500 laptop and with the last
kernels in F13, I have the problem that my laptop does not properly
resume from sleep. Most of the time, I just see the "blue screen" with
the fedora logo but nothing happens afterwards...
This happens not always but most of the time (~ 80%). No lines in the
system, the system is just "dead". Kernel is not tainted...
How can I debug that? I think before opening a bz report, I first need
to gather some data but how?
fs
Check if numlock+capslock are flashing -- if they are, kernel crashed
Check if you can switch to a virtual terminal with Ctrl+Alt+F2..F6
edit /etc/sysctl.conf and set sysreq = 1. After that, when you get a
freeze, try using REISUB (
