Red Hat Bugzilla – Bug 3009
Kernel appears to panic when shutting down.
Last modified: 2008-05-01 11:37:50 EDT
A strange screen appears just before the system shuts down.
This appears to be a dump of registers and/or memory.
If someone would tell me how to capture this (it seems to
be more than one screen full.) I will be happy to pass it
This is an HP Series 4 5/133 with 48MB of memory.
The output of first few lines of dmesg.

Really need more information about this in order to determine what is
happening with the system. Please try to post the dump that you are
How would we capture the kernel dump?
I'm experiencing the same bug. I don't consider it too serious, as it
happens when the system would normally be halted anyway. It occurs in
stock RedHat kernels for both 5.9 and 6.0. Kernels that I compile
myself have absolutely no problems.

I have 2 boxes at home--one does this, the other doesn't.
On the good one, the output of halt is this (not verbatim, sorry):
INIT: changing runlevel..
Shutting down ____ (repeats a lot)
The System is halted.
(there's some new-to-2.2 "md_* awoken" messages in there, too)
On the bad system, it's the same until the last two lines:
The System is halted
Kernel Page Fault ... blah blah blah.. oops... blah blah...
So, AFAIK, the net effect is that instead of getting a single
line "Power Down", I get 2 pages of kernel error messages.
Pretty innocuous, but interesting (and ugly).
This bug is similar enough to #3100 that I'm going to coalesce.
