[parisc-linux] Cdrecord and parisc64 kernel

[parisc-linux] Cdrecord and parisc64 kernel

[Stefan Pfetzing]

Hi,

I just installed Debian/hppa on my HP Visualize C200.

After I've compiled a kernel for 64bit and tried to use cdrecord it crashed
the whole machine. It was not availible via network and din't respond any more
to keyboard requests. (btw. what key is SysRq?  Alt-Printscreen doesn't work)

The problem is, I saw noting, not on the console, and not in the syslog.

bye

Stefan

from the FAQ:

14. Can I run a 64-bit kernel on my machine ?

The answer to this is generally determined by the firmware your machine
runs. Workstations up to and including the J2240 and C360 only have 32-bit
firmware. The normal 64-bit kernel will not run on these systems. The
A500 and L2000 server only have 64-bit firmware, and these machines must
run a 64-bit kernel. The C3000 and similar workstations have both 32-bit
and 64-bit firmware and can therefore run either kernel.

A more important question is : why do you want to run a 64-bit kernel ?
Since we do not yet support 64-bit userspace, there is no advantage
to be gained running a 64-bit kernel on a machine with less than 3.5GB
of memory.

For those who do want to test 64-bit kernels on older machines, there is a
special configuration option `32-bit PDC' which will allow a 64-bit kernel
to work with 32-bit firmware. We cannot enable this option by default
as the resulting kernel will not work on machines with 64-bit firmware.

Well I've *read* the FAQ.

I've also activated that option, and YES I know it has no advantage.
I simply wanted to test if it works and what works.

So i tried to write a cd under such a kernel and it didn't work. (and I
suggest on bigger machines which need a 64bit kernel it doesnt work too
maybe?).
