3.2.0-3-686-pae kernel doesn't boot, kernel panic

2012-07-05 Thread John Magolske 
Hi,

I just installed 3.2.0-3-686-pae, but got a kernel panic when trying
to boot with it. As transcribed from my phone-camera screenshot
(there are 10 more lines of output I can transcribe if that'd help):

[ 0.987169] Kernel panic - not syncing : VFS: Unable to mount root
fs on unknown block(0,0)

Any thoughts on why this kernel isn't working?

Fortunately I was able to re-boot by selecting 3.2.0-2-686-pae from
the Grub menu. This kernel had been installed explicitly by name:

# aptitude install linux-image-3.2.0-2-686-pae

Whereas 3.2.0-3-686-pae was installed using the linux-image-686-pae
meta-package:

# aptitude install linux-image-686-pae

So something else I'm wondering...if I had initially installed
3.2.0-2-686-pae using the meta-package instead, would my recent
upgrade to 3.2.0-3-686-pae using that same meta-package have removed
3.2.0-2-686-pae?

% apt-show-versions linux-image-3.2.0-2-686-pae
linux-image-3.2.0-2-686-pae 3.2.20-1 installed:
No available version in archive

% apt-show-versions linux-image-3.2.0-3-rt-686-pae
linux-image-3.2.0-3-rt-686-pae/sid uptodate 3.2.21-3

% apt-show-versions linux-image-686-pae
linux-image-686-pae/sid uptodate 3.2+45

This is up-to-date Sid on an X200s ThinkPad.

John

Not any more than might come from a search with the error message you
have. Purge and reinstall the new kernel? Generate a new initrd? Have a
look and see what you think.

No. Which was fortunate for you. :)
