To clarify, I was simply booting with initrd.img-3.0.0-12-generic,
but kernel is Ubuntu 12.04 kernel: vmlinuz-3.2.0-18-generic .
Also, Wouter:
"When I choose kernel 3.2 in grub I'm dropped in Busybox shell. If I
enter 'dmraid -ay' and 'exit', then normal boot procedure continues."
This works perfectly for me as well! Thank You!
Now to get your fix into the initrd.img-3.2.0-18-generic. I wonder
whether it's a timing issue, or if the command is just not being run...
So the only problem I have now is that sound is only working through
the headphones (and not the notebook speakers). This is ok though.
Thanks for your help!

might be related to this. I commented there to find out.

Mine is a VPCZ13. Don't know how much difference there is
between Z11, Z12 and Z13.
While I experience trouble with the 3.2 kernel in 12.04,
Craig tells me he's running the 3.2 kernel in 11.10 without
problems (even more stable than before).
So it seems for Shannon and me that the combination Ubuntu
12.04 and kernel 3.2 is problematic.
Kind regards,

Hi,
I have a similar, albeit slightly different experience:
On my VPCZ1 (VPCZ11X9E, after hacking the bios to static
switching,
stamina) (K)ubuntu 11.10 installed nicely and everything
tested (*)
works nicely, with that kernel:
3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC
2011 x86_64
But after "apt-get upgrade" and reboot, the screen is
black on kernel
3.0.0-15-generic.
Selecting 3.0.0-12 in grub boot menu still works flawless.
So, I combine this experience with the others ones in
this thread, it
gives this strange pattern:
2.6.38-11-generic-pae works on VPCZ114GX
3.0.0-12-generic 64-bit works on VPCZ11X9E
3.0.0-15-generic 64-bit fails on VPCZ11X9E
3.0.0-16 works for Wouter van der Graaf
3.2.0-18-generic fails on VPCZ114GX
Could it be an (another) upgrade problem instead of a
kernel problem?
(*) tested to work:
- Stamina graphics 1600*900
- VGA out
- Sound
- Wireless
- 1gbit/s ethernet
- SD card reader
- Sleep, hibernate and resume
- Brightness keys
- Touchpad
- echo 1> /sys/devices/platform/sony-laptop/kbd_backlight
Kind regards

Hi,
Same problem here. I upgraded 11.10 to 12.04 and
exactly the same error,
dropping me in a BusyBox shell. Luckily I still have
the 11.10 kernel
3.0.0-16, so booting with that kernel solves it for now.
So it seems there's a regression in the 12.04 kernel.
Does anyone recognize
this issue? Any suggestions on how to find the cause?
Thanks!

Hi, I hope this is the right place to ask for help..
I've been using Ubuntu 11.10 GNU/Linux on my Sony
Vaio VPCZ with success
- I wrote up the few steps I took to make it work
for me at: http
://linux-on-sony-vaio-z.wikispaces.com/VPCZ114GX
<http://linux-on-sony-vaio-z.wikispaces.com/VPCZ114GX>
But now, I've i3.2.0-18-genericnstalled Ubuntu
12.04 and it won't boot... Can't find the
root device at /dev/by-uuid (nothing shows up in
there), then drops to
busybox. I've tried a rootdelay=160 and that
doesn't help. I also tried
replacing the UUID with the path to
/dev/mapper/isgwXXX-blah-blah but no
success.
What's crazy is that the Ubuntu 12.04 runs
perfectly on this computer
from the LiveCD, that's how I installed it on
here. Would be nice if
Ubuntu did some kind of sanity comparison check
between the running
LiveCD system and that which gets installed. One
thing I did notice
that is weird though is that the partitions in
/dev/mapper/isgwXXXXX are
listed twice in the 12.04 installer.. This is
different then when
installing 11.10 - where there's only one set of
partitions listed
there. I made sure to install the grub on the
base /dev/mapper/isgwXXXX-
blah device so I don't think it's a grub problem.
And when I inspect the
UUIDs of the drives in the installed grub.cfg -
they match to those
listed for the partitions when I run the LiveCD.
So here's how I'm booted into this system now...
I went and reinstalled
Ubuntu 11.10 to my separate root partition, then
I copied over the
/boot/initrd.img-3.0.0-12-generic to my separate
/home drive that has
been preserved the whole time. I then reinstalled
12.04 to my root
partition, backed up initrd.img-3.2.0-18-generic,
copied
initrd.img-3.0.0-12-generic with a rename to
/boot/initrd.img-3.0.0-18-generic and the system
now boots. There are
some error messages from the land of /lib that
show during startup, and
sound doesn't work, but the system boots and
that's how I'm submitting
this.
So.. is it a initrd.img-3.0.0-18-generic problem
that's causing my
Ubuntu 12.04 system to not be able to see the
root device on boot and
thus dropping me to busybox instead, or what? If
so, how do I fix this?
I get the feeling that using the
initrd.img-3.0.0-12-generic with the
3.0.0-12-generic kernel is causing my sound not
to work.. and I'm
thinking when I get a kernel update I'm going to
be whacked back to not
being able to boot... So does anyone have any
suggestions? This is a new
horizon for me. I love this stuff. And, I love
all of you for the
awesome things you do for this awesome OS.. Thank
You! and Thanks for
any help you can provide!
