I just compiled the 2.6.38 linux-image Debian package from source on

I don't know if that was actually necessary, as the linux-image package
from unstable seems to install directly.
It should work, yes.
Good to know.
Regardless, both the backported and original linux-image packages have
two dependencies which are not in squeeze. These are linux-base (>= 3~)
and firmware-linux-free (>= 3~). See the apt-get error message below.
The versions of these in squeeze are both 2.6.32-31. So, my main
question is, is it safe to upgrade these ie. can I upgrade them without
breaking my current 2.6.32 (default) kernel?
Yes. They have to be kept backward-compatible, so that upgrades from
'squeeze' to 'wheezy' will work.
Thanks, that's very helpful.
Also, I just tried to run 2.6.26 (still installed from when I was running
lenny) but it crashed and dropped down to the initramfs prompt. I don't
have the error message handy right now, but could get it. I just want to
know if I am missing something obvious. Should 2.6.26 continue to work on
squeeze without problems, or not?

No, see
<http://www.debian.org/releases/stable/i386/release-notes/ch-upgrading.en.html#upgrading-udev>.
Ok. Is the only problem with the lenny 2.6.26 that it has
CONFIG_SYSFS_DEPRECATED enabled? Or are there other problems?
I am seeing some failures in the 2.6.38 installation. See output below.
Specifically, some problems with nvidia and virtualbox. I tried booting
with .38, and it does boot, but compiling the nvidia module fails, and m-a
is not particularly helpful when outputting errors. Should I upgrade the
nvidia stuff to that in unstable? Would the unstable nvidia compile Ok
with 2.6.32? Ie. is it backward compatible?
I don't know what to think about virtualbox. I didn't try compiling the
modules. If I need to use the unstable version on squeeze, it will need
backporting from unstable. There are some C++ incompatabilities with the
version in unstable.
Additionally, I was seeing the following errors thrown on the console.
"No human readable MCE decoding support on this CPU type
Run the message through 'mcelog --ascii' to decode."
Should I file bugs against any of this?
Regards, Faheem
