NOTE: This issue has been resolved in the RHEL3U5 preload. If you are using RHEL3U3 or RHEL3U4
preload, then the following resolution still applies.
HP recommends you configure the accelerated driver as follows as root:
Change to the needed directory:
# cd /opt/hp/graphics/nvidia
Run the configure script:
If you are running with 4GB of memory or greater, run the script to add the needed entry to your
# perl nv_swiotlb.pl
At "Attempt to add /boot/grub/grub.conf entry (y/n):," answer Y.
If you are running with 4-4.5GB of memory, you will need to make one additional change to work
around a possible panic:
Increase or reduce your memory so that you are above or below the 4-4.5GB boundary. This
can be accomplished by any one of the following:
Modify your /etc/grub.conf and replace swiotlb=16384 with mem=4000m. This will
force your kernel to behave as if it has only ~3.3G of memory.
If possible, remove memory to get to 3GB or lower. (The memory sticks need to be
removed in pairs).
If possible, add memory to get to 5GB or higher. (The memory sticks need to be added in
Reboot you system:
