I have a laptop which doesn’t have a brandname. It is a ‘china make’ and I think is assembled laptop. This laptop uses a promise SATA card, to which a harddisk is connected. So, during booting it requires a promise SATA card driver, otherwise Harddisk is not detected properly. I faced this problem with Windows and Linux installation. I could install linux in 3rd attempt. Anyways now the problem is that when i recompiled kernel 2.6.15.4 on the same machine it gives the following kernel panic message:

************************************************** **************

What could be the reason for this??

kernel /boot/vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/ rhgb quiet

kernel /boot/vmlinuz-2.6.15.4 ro root=/dev/sda5 rhgb quiet

Considering that the kernel compilation went fine I can recommend that you should try out "root=LABEL=/ " for your compiled kernel also

regards

I have already tried with that but it doesn't work either. It was only after it failed i tried making root equal to the device (/dev/sda5). Can you suggest some other alternative?

Do you have suport for ext2 FS built in your kernel??

follow this thread too,I think you can get some good directions here

https://www.redhat.com/archives/atar.../msg00018.html

regards

I may be wrong but don't you need in fstab:

/dev/sda5 / ext3 defaults 1 1

???

Sören

well the line

LABEL=/ / ext3 defaults 1 1

in fstab files says it all

Here tha partition that has been marked as root will be used mount at /

the problem can arise if you more than 1 partition marked as root

regards

Why does it say:

Root (hd0,4)

Filesystem type is ==>ext2fs<==, partition type 0x83

And here:

Kernel /boot/vmlinuz-2.6.15.4 ro root=LABEL=/1 ==>rootfstype=ext3<== enforcing=0 rhgb quiet

Shouln't:
kernel /boot/vmlinuz-2.6.15.4 ro root=/dev/sda5 rhgb quiet
Be:
kernel /boot/vmlinuz-2.6.15.4 ro root=LABEL=/ rhgb quiet

???

I had suggested the same in my first post

regards

Well ext3 is notjing but ext2fs with journalling support
