Description Leek Soup 2011-03-13 22:52:56 UTC

Description of problem:
I updated my FC14 installation and now suspend is broken. Hibernate does not work on either old or new FC14 kernels.

Version-Release number of selected component (if applicable):
kernel 2.6.35.11-83.fc14

How reproducible:
Suspend never works with new kernel (version above). It works consistently with the older (2.6.35.6-45.fc14).

Steps to Reproduce:
1. yum update kernel (will update to 2.6.35.11-83.fc14)
2. suspend using System->Shut Down...->Suspend
3. 
  
Actual results:
Screen goes blank but system does not properly suspend. Power light stays on instead of flashing. I can "see" a tty by using Ctl-Alt-F2, but when I try to log in, it does not respond at all. I have to hard power down and reboot to get back to working.

Expected results:
System suspends when I use the suspend. It resumes when I briefly touch the power button.

Additional info:
Suspend does work with the originally installed version from the Live CD, kernel 2.6.35.6-45.fc14

Hibernate does not work with either kernel on this machine, but it is rare for hibernate to work for me. Out of a half-dozen systems I have installed Fedora on over the years, hibernate only worked consistently on one.

I am not sure what additional info you need. Pls let me know and I will post.

It would help if you could try 2.6.35.10-74. You would have to manually install it from koji:

I have never done a manual install. What would I have to do?

I figured it out and tried it. With this koji kernel (2.6.35.10-74) suspend does mostly work. Here is what happens.

1. System->Shut Down...->Suspend
system suspends
2. push the power button to resume
Fedora splash screen appears and stays there.
If I press <Ctl><alt>F2 I get a working terminal.
If I then press <ctl><alt>F1, it returns to normal GUI operation.

The only strange part is that I have to switch to tty and back to make things work.

No. This bug is already present in kernel 2.6.35.11-83.fc14, unlike the one you link, which appears *after* this version.

Just installed FC15 2.6.38.7-30.fc15.x86_64. Suspend works again, so this bug is not important for me any more.
