After a quick search of BugZilla it seems that this is a known issue (bug
12904) and there is a work-around - add the following to the boot command line:

I've added a link to this page on the BugZilla bug. Thanks one and all for the
support on this so far - hopefully

Ben, thanks for testing and the feedback. Would you be willing to also
open an upstream bug report at bugzilla.kernel.org since you've been
able to reproduce the issue on an upstream kernel? If you could post
the link to the upstream report here for others to also track that would
be great.
Hi Guys,
Would you be willing to test the latest mainline kernel build,
2.6.30-rc8 as of this posting.

We'll want to open an upstream bug report to make sure the upstream
developers are aware if this does exist upstream. Otherwise we'll want

Just tried the new kernel (2.6.30-rc8 amd64) and the symptoms are exactly the
same. It would seem that this bug is probably a mainline issue.

I've tried with the Vesa driver and I get exactly the same behaviour -
this is almost certainly a kernel bug.

From the comments in the freedesktop bug (#205) it seems that it is
really a hardware bug in the Sony Vaio computers. It may be possible to
work around it, but I'm not sure in which package. It could be ACPI,

Okay, so since there are no messages around 09:37:03 and the first

this is a kernel bug or not. Do you have the possibility to perform the

I agree, it's looking more and more like a kernel bug. I have added the
package linux to this bug report. For kernel bugs there is a whole new
list of required information (see

to upload the output of `uname -a`, `cat
I just came over bug 213191 which has a similar issue (though this was
on switching to external, not on connecting). I haven't read it in
detail yet (and I have no more time today), but in that case it looks
like it is still a driver bug, even though CapsLock and network does not
respond.

Also I'm impressed that you could ping your computer

you do that?
A friend with a Windows laptop was using the network - he didn't want to
install an SSH client (work laptop), but could ping from the command
line as that functionality is
After a lock-up caps lock does nothing (no response from LED).
Connecting the monitor while in console mode shows no output - no
response from keyboard, no stack dump, no panic.

This smells a bit like a bug in the kernel, an X-driver bug shouldn't be able
to freeze the system completely. There are a few tests you can do to find out
this, and we would be interested in the result of all of them.
