Another possible test, although it's the worst case scenario - compile your own kernel only using the patches from the SRPM you really need. Sometimes RedHat kernels actually break the real kernel in obscure ways. Historical anecdote: back in RH73, the Intel L440GX+ motherboard (server mobo) was everywhere. The initial 7.3 kernels worked fine, then along the way they broke - no L440GX+ motherboard would work anymore. At that point I had to run hand-compiled kernels on all the servers (same core version as RPM patched ones) and it worked perfectly fine. Eventually newer kernels came out that at least worked with 'noapic' on the boot line (still have a few running, knock on wood), but unpatched kernels worked just fine without this as before. There's a mile-long bug buried somewhere on the redhat.com bugzilla. So, there is some history of RedHat patches breaking a perfectly good kernel - you may possibly be in this situation, but it's a real bugger to figure out. -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com
