Must specify RAM size to get kernel to boot
Last modified: 2008-08-02 19:40:36 EDT
Description of problem:
Boot will hang up when either installing or booting after install if I do not
specify how much RAM I have.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try to boot kernel w/o mem=4G. Locks up.
Either the install program should run or you should get to login prompt (after
Pentium Core Duo 2 (~1.66)
SATA ACHI mode 300GB x 3
I must pass "nodmraid mem=4G" to get kerenl to boot cleanly. This bug is only
against having to specify RAM size.

1) Is kernel 2.6.18-1.2798.fc5 or 2.6.18-1.2798.fc6?
2) From the additional info, it is an i386 machine instead of ia64.
Could you post your dmesg using mem=4G. Also if you have a digital camera,
remove the "quiet" from the kernel cmdline and take a picture of the lockup.
Did this work before 2.6.18-1.2798.fc5 or did it never work?

I guess processor may really be 32-bit, but I'm running 64 bit Linux and Vista
without a problem. (well other than the one above)
So it's a x86_64 machine, not an Itanium (IA64) machine.
Sorry, my mistake.
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug, however this version of Fedora is no longer
Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.
Thanks for using Fedora!
