Hi Michael, > Greetings. One of the profs here has got a Dell Optiplex 620 > running SL > 4.4. It has an Intel Pentium D chip that is dual-core-capable, and > it has the capability enabled. > > >From time to time the owner has had problems with the system hanging. > He usually solves the problem with some stupid computer trick, such > as cycling the power, etc. But yesterday he had one of the usual > hangs, except that it was one from which he could not recover. > > The problem is very similar to one that was reported on the SL-users > list not too long ago. In more detail, the system either has a > kernel panic during the boot sequence, or it boots all the way and > allows a login, but almost immediately has a "hard freeze" that > requires a power cycle to thaw. > > We've run the Dell diagnostic utilities to test processor, memory, > and video, but we didn't find any problems. > > The system is running the latest kernel, but it will not boot reliably > with any of the four SMP kernels currently installed on it. > > We've tried all of the voodoo that I saw mentioned in the previous > discussion (run-level 3, no "rhgb quiet" on the command line), but > the only thing that seems to work reliably is to boot with the uni-processor > kernel. > > This is probably an acceptable work-around for the time being, and my > hope is that when we do a fresh install with SL 5, we'll all be happy > again.

You may have also found references on the list archives to: noapic apm=off and other such options to be added to the command line of smp kernels. Try these.
