Hi -
Running into the error below when copying over large files via ssh. This
occurs even when I have vm.overcommit_memory=2 set in /etc/sysctl.conf. The
research I've done indicates that this is a bio-uses-GFP_DMA bug with EM64T.
I'm running CentOS 4.4 with the 2.6.9-42.0.3.ELsmp x86_64 kernel on the
following hardware:
2 x Intel Xeon CPU 5148 @ 2.33GHz
Supermicro X7DB8 motherboard
Is there a patch or workaround for this, or some parameter that I can pass
to the kernel at boot? Any help would be appreciated.
thanks,
Lance
