Hi,
Many thanks for your e-mail. It appears that you are right because the
following loops incessantly, and only when I go into pm-hibernate, not
when I go into pm-suspend.
Here is the necessary output:
% top
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1589 maitra 9 -11 422m 2176 1048 R 94.9 0.1 8:48.81 pulseaudio
% strace -f -s 256 -p 1589
The following keeps on scrolling:
[pid 1589] ppoll([{fd=5, events=POLLIN}, {fd=21, events=POLLIN}, {fd=9, events=0}, {fd=4, events=POLLIN}, {fd=20, events=POLLIN}, {fd=26, events=POLLIN}, {fd=31, events=POLLIN|POLLERR|POLLHUP}, {fd=31, events=0}, {fd=30, events=POLLIN}, {fd=29, events=POLLIN}, {fd=22, events=POLLIN}, {fd=25, events=POLLIN}, {fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15, events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN}, {fd=13, events=POLLIN}, {fd=7, events=POLLIN}], 19, NULL, NULL, 8) = 1 ([{fd=9, revents=POLLHUP}])
Killing pulseaudio (the process) seems to take care of it, and the
temperature cools.
Once again, I am running the F14-LXDE spin.
Many thanks,

F14: high temperatures after coming back from hibernate
by Ranjan Maitra
Hi,
I have noticed a strange problem after I come back from hibernate and
upgrade in F14 on my Thinkpad T61. The temperatures are off the charts,
hitting as high as 95C, and staying there, soon after waking up. The
laptop has become unusable, basically. Here is the output of top: the
topmost processes. Note that the laptop has 4 GB of memory,

Any suggestions? What sort of bug report should be filed. Is there a
fix, beyond removing gmixer (816 MB, when nothing is running)!
This problem does not happen if I reboot (or go in fresh) even if I
stay up for hours. So my first instinct that the fan had failed or
something does not seem right. (The fan is groaning now.) I have not
tried suspend yet.
I am using the F14 LXDE spin. I believe that the problem may have
happened also towards the last week of F13, however I had not connected
the correlation with hibernate at that time.
Best wishes,

F14 LXDE spin lxdm-greeter does not go anywhere....
by Ranjan Maitra
Hi,
Just installed Fedora 14 LXDE spin on my trusty IBM T61 Thinkpad laptop.
It was a clean install, however after install, I can not get beyond the
login screen.
Here is what happens:
I input my user name for the Username:
hit enter
and then my password next to Password:
Both go away, but the big Login screen does not. (Basically nothing
happens). Hitting the quit button to reboot/shutdown causes a flashback
to the first login screen (and then the above process is repeated with
amazing regularity).
Going in to console mode and logging in shows lxdm-greeter as a process
running. Nothing else is out of the ordinary.
Any suggestions?
