Red Hat Bugzilla – Bug 237239
Kernel Panic during during installation Kernel 2.6.18-8.el5xen x86_64
Last modified: 2009-02-13 13:09:38 EST
Description of problem:
After starting an installation with any of the following commands a kernel panic
takes place when the "northbridge chipset memory remapping" feature is enabled
(2 memory blocks each of 2GB, total installed 4GB):
-> linux mediacheck
-> linux noprobe
-> linux acpi=off
-> linux pci=nommconf
-> linux mem=3072MB (to) linux mem=2080MB
In contrast, an installation with "linux mem=2048MB" and less memory succeeds!
The installation succeeds too, if the "northbridge chipset memory remapping"
feature is disabled (1 memory block of 3GB, total installed 4GB).
Version-Release number of selected component (if applicable):
Kernel 2.6.18-8.el5xen x86_64
Steps to Reproduce:
last regular message on the screen: io schedular cfq registered.
an error message on the last screen: oops_end + 0x51/0x53

This bug is very old now, and RHEL-5.0 is fairly old too. Can you give 5.1 a
try and see if you still have the problem? If you do, please get a complete
OOPS trace and attach it here (serial console is the easiest), and let us know
the exact version of the kernel you tried.
No response to need info for almost a year. Closing this out. Please reopen if you can reproduce the issue.
