Description of problem:
On bootstrapping, the system boots from GRUB perfectly well until it
comes to the section shown in the attached file. It sits there after
the message 'Freeing unused kernel memory: 136k freed' and requires a
reboot to.. produce the message again. I have also tried booting with
linux nofb, to no avail. Any help you can provide would be greatly
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Turn on machine
Actual Results: Hangs after mentioned message
Expected Results: Loads Fedora Core 1
Created attachment 96655 [details]
Output of the loader messages before GRUB hangs
Attached are the messages I get before GRUB hangs.
As a sidnote, this also occurs on Red Hat 9 (Shrike) whilst using the
LILO boot mngr. When I can get it into a rescue shell (its not doing
it right now, for some unknown reason) I will attach
my /etc/lilo.conf for you.
apm=off is most likely workaround; if that fixes it your bios can't
handle apm idle calls even though it advertises it can
I am seeing this on my machine too, I have three different kernels
(from progressive kernel updates) in my grub config, and all three
hang at this same spot.
Fails on mine as well (last 2 arjanv kernels). apm=off has no effect.
Can confirm this on my dell C600 (PIII) laptop. apm=off did not help.
One more comment - it only happened when I upgraded to the 2.6 kernel
(Fedora Core 2)
Are you using FC1 userspace ? or old FC2 glibc ?
Does booting with vdso=0 fix it?
My machine is arjanv kernels on FC1. vsdo=0 deos fix it.
I have gotten this error on a Dell PowerEdge 2650 running Redhat EL
3.0. It boots fine with kernel-smp-2.6.4-1.302 but not with
kernel-smp-126.96.36.199-1.349 (or a couple others I've tried from
people.redhat.com/arjanv inbetween 2.6.4-1.302 and 188.8.131.52-1.349)
Same freeze at 'Freeing unused kernel memory'
Well, stupid me posted this in the Fedora section, rather then the EL
section, but either way, the vdso=0 does fix it. Sorry for the wrong
My system also hangs after the messaged 'Freeing unused kernel memory'.
I am using 2.6.7-1.448 kernel. where should i add vsdo=0? What does it
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
