smp kernel panics on boot with quad-core HP xw6400
Last modified: 2007-11-16 20:14:55 EST
Description of problem:
When booting smp kernel on HP xw6400 with with two dual-core Xeon 5160's the
kernel panics (using noapic didn't help). The uniprocessor kernel boots ok.
Version-Release number of selected component (if applicable):
2.6.9-42.0.8.ELsmp, 2.6.9-42.0.3 Didn't work either
Boot computer with smp kernel
Steps to Reproduce:
Kernel boots normally
Kernel boot log attached

Kernel boot log
Dual-core (and Quad-core) support has been one of the things worked on for U5. Can you give one of the
pre-U5 test kernels a try?
Recent kernels work rather well internally on an xw6400 here in the office.
Tried kernel-smp-2.6.9-46.EL.x86_64.rpm and it boots normally. Probably will
also work fine.
Strange thing, though, is that that upon boot of the new kernel kudzu found a
"new" device: 'Intel Corporation 631xESB/632xESB IDE Controller'.
hmm, does this message come up on every boot, or just the first time?
The new device message hasn't show up in subsequent boots. Also, all kernels
after 2.6.9-46 have worked fine.
As far as I am concerned this can be closed as fixed.
