Kernel panic - not syncing: VFS after Kernel 3.8.6 update

[FONT=tahoma][size=2] Hi everyone.
Today updated tumbleweed and with that I got the kernel 3.8.6.

After restarting, got the kernel panic “not syncing: VFS” Want to know if there is people with the same problem and if someone can help me with that. Was reading stuff around about how to fix it, but it’s better to ask someone rather than risking the installation.

Thanks in advance (later I’ll post more info, but it’s late now.)

If all is well, you should be able to boot the old kernel through the advanced boot option.

#3

tried that already, but there’s no old kernel (3.7 right?).

#4

Check the Grub 2 Advanced boot selection menu on restart. Kernel versions will be listed there.

Thank You,

There’s only 3.8.2-6-desktop :/.

This is what I get when I try to boot

[FONT=tahoma][size=2]Installedthe kernel 3.7.10 through the 12.2 installation DVD + Repositories and that solved my boot problem,however can’t upgrade to 3.8.6-2-desktop.

Thanks for your help guys.

So I am not sure what is wrong with the Tumbleweed kernel, but kernel 3.8 is a good version. There is more than one way to get a new kernel including to compile your own. Have a look here: openSUSE and Installing New Linux Kernel Versions - Blogs - openSUSE Forums

Thank You,

Was thinking about that (also great post). Tomorrow will compile the kernel.

Thank you.

Now check these settings:


/etc/zypp/zypp.conf:

multiversion = provides:multiversion(kernel)

multiversion.kernels = latest-1,latest,running

That way you can start a kernel update, and still keep the previous one,
so that if one fails to boot, you have the other one.
