OK, here's the last video card in my drawer: VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev b2) It's an AGP card, and the system appears stable running X and KDE.
So here's the bottom line: kernel 2.6.15-26-686, and at least four earlier 686 kernels, lock up solid during KDE initialization on my dual- pIII system, Only when equipped with a Radeon 7000/VE AGP video card. Next, I may try running this combination on a single-processor system, but I'll leave that for another day. -- Fail to boot smp kernel https://launchpad.net/bugs/24533 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
