Red Hat Bugzilla – Bug 504111
Installing KVM makes machine unable to resume from suspend
Last modified: 2009-12-18 04:32:14 EST
Description of problem:
When the KVM package is installed (which loads the kvm and kvm_intel modules) suspending the machine doesn't work anymore - you can't wake it up again - it locks up. This bug was always there - since the appearance of KVM in kernel, and is present both in fedora 9 and 10.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install the kvm package
2. Reboot and log in to X11
2.5. (optional) launch some virtual machine with qemu-kvm, I have a feeling that this makes the probability of the bug higher.
3. System->Shutdown->Suspend or run pm-suspend
4. Try to wake up the computer
The computer turns on, but does not react to keyboard nor does not show anything on the monitor. Seldom it will wake up normally.
The computer should resume normally.
Tried this on two machines:
- One with a Core2 Duo E6400 CPU (2-cores)
- One with a Core2 Extreme CPU X9650 (4-cores)
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
