Help: Kernel Panic:VFS: Unable to mount root, after rebuilding kernel

Post by Mihail S. Iot » Mon, 04 Apr 1994 07:04:05



I get the followint message when trying to load a new kernel :

Kernel Panic:VFS: Unable to mount root.

This happens, exactly when it should say : "partitionc check hda1 hda2 hda3"

I have checked with rdev and the new kernel does have the rigth
root device (/dev/hda3). If I change this to /dev/hda1, which is my DOS
partition I get : root mounted MSDOS is read only, should be read/write
and the system hangs.

I have played with rootflag in the zImage setting it to 1 (it was 0 originnaly)
and I saw it was 1 in /vmlinuz but that did not change anything.

Moreover the new kernel is about half the size of the old :

-rw-r--r--   1 root     root       121348 Apr  2 13:43 /usr/src/linux/zImage
-r--------   1 root     root       281092 Apr  1 21:43 /vmlinuz

Finally, when I first chose SYSVIPC, when configuring it (I don't know
what it is) it would not compile :

make[1]: Entering directory `/usr/src/linux/ipc'
gcc -D__KERNEL__ -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe -m486

I recompiled with disabling sysvipc

 
 
 

1. Help: Kernel Panic: VFS unable to mount root fs

I installed RH 6.0 successfully several times on my ACER Notebook TravelMate

However, every time after booting PC the second or third time into Linux,
the following error occurs and Linux stops right there at boot time:

VFS: Cannot open root device 00:30
Kernel Panic: VFS: Unable to open root fs on 00:30

Can any expert please advise the cause of the problem?

Thanks in advance.
