Can now confirm that the same thing happens on a dual Opteron under FC3 kernel
770 under x86_64.
Comment 3 Tom Wood 2005-06-02 15:39:15 EDT
Has done the same up through 2.6.11-1.27_FC3smp.  UP kernels don't exhibit this
Comment 4 Dave Jones 2005-07-15 15:56:56 EDT
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.
Comment 5 Tom Wood 2005-08-08 14:14:05 EDT
Still occurs on this platform with every FC3 and FC4 kernel to date.
Comment 6 Dave Jones 2005-09-30 02:33:39 EDT
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel ( As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.

Comment 7 Dave Jones 2005-11-10 14:33:31 EST
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.
