Linux Nvidia: NVRM: GPU at 0000:01:00.0 Has Fallen Off The Bus Error and Solution

last updated in Categories ,

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.

Feb 19 06:14:01 wks01 kernel: [28508.567838] 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?

Linux Kernel panic VFS Unable to mount root fs and solution

last updated in Categories ,

Q. I am using Linux on HP server and I am getting error that read as follows:
Linux Kernel panic: VFS: Unable to mount root fs

How do I solve this problem?

A. Most modern distributions including Debian uses loadable kernel module for ext3 file system. So to read ext3/ext2 file system kernel must load ext3 kernel module (ext3.ko).

This module is included in an initrd image. If an initrd image is missing or that image does not include suitable kernel modules to access the ext3 filesystem on the partition, an error message (Linux Kernel panic: VFS: Unable to mount root fs) will be displayed to you.

To solve this problem you need to use mkinitrd script that constructs a directory structure that can serve as an initrd root file system.

The instructions for creating initrd images are here on our site.
