I have this problem with a node: it runs fine with kernel 2.6.18-ovz028stab053.5-smp but can see only 4GB out of 8. Therefor I installed 2.6.18-ovz028stab053.5-enterprise which can see all 8GB but is very slow after initializing udev. The system is so slow it is not usable (about 10 minutes until the login prompt). This is a Core2Quad with an Intel DG33BU mainboard (not defect, but I had to add pci=nommconf for a successful boot.

I tried it with kernels 2.6.18-53.1.13.el5.028stab053.10ent and 2.6.18-53.1.13.el5.028stab053.10PAE with same effect.

Is this a known effect?
Is there any boot option to solve this issue?

Here are the software versions, output of dmesg and dmidecode:

PAE is known to be slow, why not run a 64-bit system?

I have a lot of PAE systems running, but this is something different. The slowness of this system is translated as "not responding anymore".

This is a productive system. No way to install a 64bit system.

This maybe an MTRR issue. I experienced that after a BIOS upgrade on a DG965WH. The system boots so extremely slow that you could think it stopped responding at all, something like 10 seconds for each line of kernel output with pauses of 5 minutes in between sometimes. This is the effect of a BIOS bug, maybe an upgrade helps for you.

Have a look at this thread: http://forums.fedoraforum.org/showthread.php?t=157232 Note that they're talking about 64bit Linux, but this affects 32bit also.

Kernel 2.6.25 includes a workaround which detects this issue and uses only so much RAM as possible without a slowdown.
