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...
Did we ship bigmem kernels earlier during FC1?
I could not find a bigmem kernel on the CDs or in any of the released
The smp kernel has PAE.
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.
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.
should be fixed in the current errata kernel
