For one who suffering Kernel Panic VFS: cannot open root device
 

I've facing this problem



VFS - can'topen root device "307" or unknow-block(3,7)
please append a correct "root=" boot option
kernel panic -not syncing vfs unable to mount root fs on unknow-block(3,7)



Here is the solution

First find the way to ur root partition

in my case,Slackware i've boot up the installer-DVD , mount the root partition
, and restore old kernel

c my thread here , for restoring old-Kernel ,it'd be use on any distro (may b?)

recompile ur kernel (the one that got "Kernel Panic")

makeing config by "make menuconfig"

Device Driver->
ATA/ATAPI/MFM->
Generic PCI IDE chipset, PCI IDE chipset support, Generic/default IDE chipset support .

File System -> Ext3.

save the config

compile & install it normally & run "lilo"

(for confirm again that lilo 's reconfigure,normally "make install" will do this for us)

reboot

this should fix that problem :D
