I‘m using NVIDIA UNIX x86_64 Kernel Module version (driver) 280.13 under Debian 64 bit Linux with Linux kernel 2.6.32-5-amd64 x86_64. However, I’m getting the following errors in my /var/log/messages file

Feb 13 05:53:39 wks01 kernel: [26652.425207] NVRM: GPU at 0000:01:00.0 has fallen off the bus.

This error occurs randomly and my laptop goes in hard freez mode. The hard reboot is the only way to recover from complete freeze of my Dell M6500 Debian Linux based laptop. How do I fix this problem?
