VFS: cannot open device "sda2" on unknown block(0,0)
Last modified: 2007-11-30 17:11:43 EST
Description of problem:
The boot drive is sda, the boot partition is on sda1, and / is on sda2. But
the error indicates that the sda2 partion cannot be opened. The rest of the
message states, "Please append a correct "root=" boot option. Then the system
halts at a kernel panic.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Load OS
No Kernel Panic
This is using a HP a1450n with a SATA drive. refer to the link below for
hardware details. http://www.shopping.hp.com/webapp/shopping/store_access.do?
I haven't checked, but my suspicion is the SATA (Nvidia) driver is set to load
as a module by default. The grub.conf looks alright.
Something is horribly wrong with anaconda in test3. On all the systems I've
tried installing so far, it fails to install an initrd.
If you boot to rescue mode (boot the CD with 'linux rescue'), /mnt/sysimage/boot
has no initrd present.
