Kernel panic when update 2.6.19

Hi all,

Perhaps it's an old question, but there's still some trouble for me to resolve it.

In my CentOS3.5(On vmware),recompilied to the lastest 2.6.19.1 kernel and then reboot, the following error messages display:

Code:

VFS: Cannot open root device "sda3" or unknown-block(0,0) 
Please append a correct "root=" boot option 
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Here, /dev/sda3 is my "/" mounting point.

I searched in google,and this forum, refer to :

Check the "/usr/src/linux-2.6.19.1/.config", the buglogic is enabled. Review "/etc/fstab", it is "/dev/sda3" and I need not to change "hda" to "sda".
These two test all failed.

Would you please give me some advance?
Any suggestion would be appreciated.

Regards,
Phillip

Make sure your relevant drivers are compiled in...

sda denotes scsi, so check that along with the correct chipset drivers for your mobo

Thank you, Rob. I've already fixed this issue.

The virtual OS is built on SCSI disks of vmware, and the SCSI controller is buslogic. It sounds to have to, when issue "make menuconfig", ensure the following items are built in:

Device Drives -> SCSI device support <*>
Device Drivers -> SCSI device support; SCSI low-level drivers
->Buslogic SCSI support <*>
Fusion MPT Service support <*>
Fusion MPT(base+scsihost) devices <*>
Fusion MPT device (ioctl) drivers <*>
Device Drivers -> USB support <*>

And, In File Systems, both "ext2" and "ext3" are also built in.(Or you'll meet "Kernel Panic: no init found" when boot from new kernel).

I'm annoyed by installation in vmware for two days, and have done more then 10 times test, perhaps my resolution is not the best way, but I think it will give us some minds.

Regards,
Phillip
