Unfortunately this is not an option which can be done with anywhere realistic effort. I do not deny this for fun, but it is an unreasonable request on our time. It will both disable userland threads (PCI support uses them), and make absurd workarounds necessary to keep kthreads working (because the shared memory driver usage relies on udev too). sorry. - Michael > > There is no need to maintain debs beyond 2.5.3 for sure, but users should > still be able to build a RIP install from the 2.6 sources. > > (This has probably prompted me to try building a single processor targeted > 3.xx kernel on debian, as a contingency for my older hardware) > > regards > > > > ------------------------------------------------------------------------------ > Get 100% visibility into Java/.NET code with AppDynamics Lite! > It's a free troubleshooting tool designed for production. > Get down to code-level detail for bottlenecks, with <2% overhead. > Download for free and get started troubleshooting in minutes. > http://pubads.g.doubleclick.net/gampad/clk?id=48897031&iu=/4140/ostg.clktrk > _______________________________________________ > Emc-developers mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-developers ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
