Errors compiling

boombastic · 08-03-2004, 04:24 AM

I'm trying to compile kernel 2.6.7 patched with 2.6.8 rc2 on FedoraCore2.All goes ok but when i reboot i get these errors:

RAMDISK: incomplete write (-28!=32768) 4194304

KERNEL PÈANIC:VFS: unable to mount root fs on unknown -block (0,0)

What do they mean?How can i correct them?

How big is your ramdisk and have you run out of room on it?

I am a TOTAL newbie:how can i see the size of the ram disk?And what does it mean "out of room"?

Run out of room...as in 'no space left'. You can type df to see the amount of space left on the drive, but if you're using a ram disk you'll have to do it when you get the error because it gets wiped each time you restart the computer.

Well:i removed the support to the RamDisk during the configuraion of the kernel so i get the error about it no more but still i geet the kernel panic and don't undeerstan what you advise to do,sorry,can you explain again?

OK....what filesystem do you use? Did you use ReiserFS, Ext3 or Ext2 when you installed fedora? Because what I think (this is just an educated guess, it may be wrong) is that you've got either a ReiserFS or Ext3 root filesystem, but you haven't compiled support for that system into the kernel...therefore it can't mount your disk at startup.

Like I said, I could be wrong.

The fs is XFS and i checked all the options about it during the configuration of the kernel.I think that anyway the problem is there because when i compiled tje kernel with ext3 as fs i had no problem.Any other advice?

Try to use initrd.
You can find all the information in /boot/initrd.README.
It was my saver.
Good luck
