Description azmodai 2008-04-06 11:31:54 UTC
I've got a strange boot problem :
The boot process fails during the kernel loading and displays : 
Root-NFS: No NFS Server available giving up.
VFS : Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy ans press ENTER 
Then I press ENTER without inserting a floppy and I get : 
VFS: Cannot open root device "sda1~" or unknown_block(2,0)
Please append a correct boot "root=" option ; here are the available partitions :
0300-419302 hda driver : ide-cdrom
0800-195360984 sda driver : sd
..... sda1
..... sda2
..... sda6 
I have a different root device name each time I boot ! i.e: There I've got : "sda1~" but I can get "sda1vdp" or something else ....
That's very strange .... 
I've got that problem since yesterday (5 april) just after updating my whole system. 
Therefore I decided to build the latest kernel thanks to another kernel that allowed me to boot normaly.
I built it : everything worked out just after and now nothing works even if I try to boot with my old kernel .....
After that I decided to check my sda1 partition with : "ext2fsck -c /dev/sda1 and ext2fsck -y -v /dev/sda1 and badblocks /dev/sda1"
It did no change anything.

I don't understand very well because sometime I can boot correctly although I cannot most of the time .... 

But when I remove "root=/dev/sda1" from the grub config file I can boot  ! 

Maybe it's a problem due to the update I've done yesterday ?
(read my forum post in order to get more details)

This kernel or that kernel - be exact please. Same goes for the bug subject.

I've got these problems with 2.6.24.2 and 2.6.24.
Comment 3 azmodai 2008-04-06 16:24:49 UTC
sorry it's 2.6.24.4 not 2.6.24 (sorry for flood)
I don't use gentoo kernels , I build it from tarballs.
