Description Jesse Keating 2004-05-06 19:54:51 EDT

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
This is a RFE, currently there is no stock way of supporting more than
4gigs of ram.  This is a fairly big issue for us as we sell lots of
servers with +4 gigs of ram.  Seems that the building of bigmem was
just turned off in the spec...
Comment 1 Warren Togami 2004-05-06 20:18:33 EDT
Did we ship bigmem kernels earlier during FC1?
Comment 2 Jesse Keating 2004-05-06 21:16:59 EDT
I could not find a bigmem kernel on the CDs or in any of the released
Comment 3 Arjan van de Ven 2004-05-07 02:45:38 EDT
The smp kernel has PAE.
Comment 4 Jesse Keating 2004-05-07 10:35:50 EDT
I'm almost dead positive that we had the smp kernel on the system, and
only 4 gigs showed up.  I built the bigmem kernel and then 6 gigs
showed up.  I'll have to double verify this, but can you also check on
your side?  The config files packaged with kernel-source show that
config_bigmem_4g is configured for the smp, not 64g.
Comment 5 Jesse Keating 2004-06-09 14:25:25 EDT
I can conform that 2188 smp does _not_ have PAE enabled.  It only sees
a little under 4 gigs of ram on a system that has over 5 gigs. 
Booting  a rebuilt kernel that has PAE lets me see the full size.
Comment 6 Dave Jones 2004-07-01 16:22:13 EDT
should be fixed in the current errata kernel
Comment 7 David Lawrence 2004-09-29 16:24:22 EDT
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
