An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

Installed the new kernel-smp-2.6.12-1.1372_FC3.x86_64.rpm package but the server
now dies due to a kernel panic during boot / startup. No log just yet as this
was tested via remote hands.

I will try to schedule a reboot to test the non-smp / i686 versions and get full
error log 'soon'.
Comment 4 Vincent Sweeney 2005-07-18 09:12:17 EDT
kernel-2.6.12-1.1372_FC3.x86_64.rpm installed and boots fine. 12 hours uptime
under load so far with no 'bad pmd' or oops which is a marked improvement over
previous versions.

However the x86_64-SMP kernel still fails to boot, hope to test the i686-smp
version later.



Comment 5 Vincent Sweeney 2005-07-20 21:29:03 EDT
Well I guess I can't test the smp version (!) until bug 163437 is resolved ....
Comment 6 Vincent Sweeney 2005-08-02 12:45:30 EDT
kernel 2.6.12-1.1372_FC3smp seems to fix all issues previously seen.
Comment 7 Konstantin Olchanski 2005-08-02 18:11:30 EDT
Negative. I just booted kernel 2.6.12-1.1372_FC3smp and had two panics with
"swap_free: Bad swap file entry", see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=164941
K.O.
