Re: Do 8042/kb_ps2 keyboard devices work under wheezy kernels?

Hi all,

I'm currently working on a patchset to fix up the various OpenBIOS
properties to enable detection of the PS/2 keyboard in QEMU. After a
couple of days work I have a prototype patch which fixes us the various
device tree properties to match those close to real hardware - which
works fine on all of my non-Linux images but fails when trying to boot a
Debian wheezy kernel.

Here is the panic I get when I try and boot the kernel:

[   17.184211] Unable to handle kernel NULL pointer dereference

I think we've all seen plenty of this sort of thing over the years.

I'm afraid that it's very unlikely that I can spare time to trawl through surviving machines trying to find one with the right kind of hardware: the most likely machine went down with a Psycho failure years ago.

For the sake of anybody who does happen to have time, where are you getting your .iso image and what if any mirror are you selecting during installation?

I had no end of problems about 18 months ago trying to find a SPARC/Linux later than Lenny which was even half-way reliable, and that was a large part of our eventual decision to abandon the architecture.
