I've been recommending "the FC5 kernel" as the stable reference kernel using the old pre-utrace ptrace. Recent updates are no good for that purpose and should be avoided. kernel-2.6.17-1.2187_FC5 is the last fc5 updates rpm before the updates started including buggy utrace code. For known-stable ptrace, please use that for now or an earlier kernel that worked for you (my workstation has been up for 41 days and it's running 2.6.17-1.2174_FC5). I've asked the Fedora kernel maintainer to drop the utrace patch from fc5 update kernels, and the next update to go out will go back to the vanilla upstream ptrace (may be a few days). The safe update will have a version higher than 2.6.18-1.2243. Thanks, Roland
