Bug 435609

Created attachment 296512 [details]
Screenshot of kernel bug

Caould this be caused by trying to boot an i686 kernel on i586-class hardware?

Should be fixed by this:

Commit:     959b3be64cab9160cd74532a49b89cdd918d38e9
    x86: don't use P6_NOPs if compiling with CONFIG_X86_GENERIC

Regarding https://bugzilla.redhat.com/show_bug.cgi?id=435609#c2, not really,
kernels up to 2.6.23 i686 are booting well:

$ rpm -q kernel --queryformat "%{name}-%{version}-%{release} %{arch}\n"
kernel-2.6.23.15-137.fc8 i686
kernel-2.6.24.3-12.fc8 i686

BTW: does https://bugzilla.redhat.com/process_bug.cgi#c3 result in that 2.6.24
i686 kernel do no longer boot on VIA C3 / C7 CPUs? Then one have to adjust the
arch detection, because currently:

# cat /proc/cpuinfo 
processor       : 0

bogomips        : 1601.77
clflush size    : 32

Should I switch to i586 kernel?

Should be fixed in 2.6.24.3-14.

don't boot (see #1) on my headless "firewall"

kernel-2.6.24.3-34.fc8 has been submitted as an update for Fedora 8

Earlier i686 kernels have worked on this VIA box?  Specifically what versions?
 

Yes, kernel-2.6.23.15-137.fc8 i686 (see
https://bugzilla.redhat.com/show_bug.cgi?id=435609#c4) works.

kernel-2.6.24.3-34.fc8 has been pushed to the Fedora 8 stable repository.  If problems still persist, please make note of it in this bug report.

I just tried 2.6.24.3-34-fc8 in a VIA C3 based system.  The bug is still present :(

Revised fix is in 2.6.23.3-41

Hello,

I'm brand new to Linux and I installed Fedora 8 two days ago.  Everything worked
great.  I guess some form of auto-update ran (yum?) on my first boot and I let
that run overnight.  In the morning when I had it reboot, I received the same
crash error (BUG: Int 6: CR2 ...).  I downloaded my copy of Fedora from the
BitTorrent link on the main website.

From the startup menu (grub?), I'm able to get into the version of the kernel
that I downloaded (2.6.23.1-42.fc8), but if I let the default top choice be
selected(2.6.24.3-34.fc8), the crash repeats every time.

I've seen people posting this information above, so if it's helpful I've
provided it here.

[x@localhost ~]$ rpm -q kernel --queryformat "%{name}-%{version}-%{release}
%{arch}\n"
kernel-2.6.23.1-42.fc8 i686
kernel-2.6.24.3-34.fc8 i686

If there is a way for me to test 2.6.23.3-41 as posted in
https://bugzilla.redhat.com/show_bug.cgi?id=435609#c14, I would be more than
happy to help, but I need to know what commands to run to do so.

I've just tested 2.6.24.3-48, from
http://koji.fedoraproject.org/packages/kernel/2.6.24.3/48.fc8/i686/kernel-2.6.24.3-48.fc8.i686.rpm;
this works for me.

Cpuinfo from the working 2.6.24.3-48 kernel:
 # cat /proc/cpuinfo 
processor       : 0
vendor_id       : CentaurHauls

Can someone please push this kernel into F8 updates?

2.6.24.3-48 works for me, too now. Thank you!
