kernel panic:vfs:unable to mount root fs on 03:06
I installed Red Hat over a month ago, with the os seeming to work fine. I logged on today and received the following error:
VFS: cannot open root device "306" or 03:06 Please append a correct "root=" boot option Kernel panic: VFS: unable to mount root fs on 03:06 I have figured other problems out by myself, but this one has me stumped. Does anyone know what this is? I googled the error message and found that it isn't that unique, but the solutions were meant for people with a little higher working knowledge of Linux. I would appreciate any leads. Brian |
It usually means the partition was deleted... Maybe it's not like this in your case. Run any fdisk you have and check.

I ran fdisk from windows and, for what it's worth, the partition allocated for Linux is still there.

Hi Brian,
the fact that the partition is still around and you can see it in Windows doesn't mean that it has a valid file system. Maybe the filesystem got corrupted. The real test is whether or not you can mount the partition in another Linux system. Can you boot at all? You said it had been running for a month, that rules out the most frequent cause: people build a new kernel and don't compile ext2/ext3 support in, or have no IDE disk drivers. You didn't rebuild the kernel, did you? You can try to boot the RedHat CD in rescue mode, or, if you can still burn a CD somehow/somewhere, I have a rescue CD project at http://www.phenix.bnl.gov/~purschke/RescueCD/ (there are links to some others, which are also good), either way you can boot from the CD and check out the partition. Good luck, Martin |
