Description of problem:
Fedora 7's default kernel don't hibernate with Fedora 7
while it worked with FC6.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot on F7
2. after login on X do pm-hibernate as root
3. if I press space on the computer to shutdown after a while
4. press power button
5. and computer when should wake up don't, and after while after press key or in
lid or in power button wakes but shut down again.
on fc6, hibernate works fine
I tried build a kernel from FC6 (rpm -iv ~/kernel-2.6.20-1.2962.fc6.src.rpm
cd /usr/src/redhat/SPECS/; rpmbuild -ba kernel-2.6.spec --with baseonly
--target=i686; rpm -ivh
and using the same rpms (system) just change the kernel, boot with
kernel-2.6.20-1.2962.fc7 I don't have any problem.
I had try the new Test kernel 2.6.21-1.3255.fc7 and hibernate much better , but
after the first hibernate, computer lose the acpi events i.e. , battery status
don't change and the power management is bad. If I press lid button the screen
stay black after leave lid button, (I had to press ctrl+alt+ F1, to go to on
console and ctrl+alt+F7 to get back to X)
other thing , with kernel 2.6.21 my hard disk becomes /dev/sda instead /dev/hda
on kernel 2.4.20 , and with kernel 2.4.21 appears on dmesg, messages that hard
disks sda doesn't support DPO or FUA
The change from /dev/hda to /dev/sda is to be expected - we're using the newer
libata drivers in the newer kernels.
The loss of ACPI events sounds like an issue that has seen some work since
2.6.21 (IIRC). Are you able to try a newer kernel and see if you have better
success with it?

Yes I got this problem with kernel 2.6.21 and upper

I already try , the strange thing, now with latest updates , is computer stops
hibernation on suspend consoles, but if I press on a key (for example enter),
just after enter in suspend console sometimes hibernation is more quick and
The bigger problem now, if I do nothing hibernation process can take more than a
no "big" differences

> no "big" differences
oops , I confuse this bug with bug 8592 of kernel bugzilla.
Made more sense report here the test with new kernel kernel-126.96.36.199-76.fc7
I test hibernate from console (ctrl+alt+f1) using the kernel built-in code,
doing (suggest in Linux kernel bugzilla):
# echo disk > /sys/power/state
and no significant differences, I almost can hibernate correctly the laptop
when computer stops on "suspend consoles" if I click many times in enter and in
but after wakeup, turn computer off again it very very slow, I had to use the
technicy, press enters and spaces and waste more time than usual to shutdown.
Sorry for the slow reply.
Could you try a newer kernel again? This sounds like an issue with the NOHZ
support, which has been seeing some work. It may be that a newer kernel now
doesn't require you to keep pressing keys to get it to finish the job, and works
more reliably post-resume too.
on external reference http://bugzilla.kernel.org/show_bug.cgi?id=8592,
hibernation and suspend works on with 2.6.23+

Hi , I got same problems "require you to keep pressing keys to get it to finish
the job ..." on kernel from devel 2.6.24 and 25 rc, how know if NOHZ support is
enabled ? and how I disable it ?
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
this is fixed for me ...
