Please try the errata kernel.
2.6.12-1.1447_FC4smp came available recently.. I have installed that to see if
things are more stable.
Mass update to all FC4 bugs:
An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (18.104.22.168). 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.
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.
2.6.13-1.1526_FC4smp has been stable for me.
No signs of the original problem.
