[parisc-linux] C3600 install

[Matej Martini]

Hi

I recently bought a Visualize C3600, my first PARISC box. After playing
around with HP-UX for some days I would like to install my favoured OS ;)
on this really nice machine. FXE-graphics isn't supported so I do this via
serial line. I tried Gentoo (2.4.26-pa1) and an older Debian netinstall
(2.4.20) but I don't get far.  All I get looks like this:

---------------------------------------------------------------------------

At this point the machine seems to hang. As mentioned above this is my first
PARISC box. I'm not that familiar with the hppa architecture. Maybe it's
just a silly thing I haven't noticed. So if anyone can give me a hint I
would be glad...

This is actually a kernel problem; I also see this.... I talked to Grant
about this a bit, but we haven't reached a good conclusion. If you can
find a 2.6 based install, it should work.....

this is the bit that needs fixing, in arch/parisc/kernel/inventory.c...
with this it should boot.

Thanks for pointing me to the right direction :)

We need to shut down any devices the PDC has left in a state
where it might do DMA *Before* reprogramming the IOMMU.
Knowing which devices to shutdown this early and how to access
then is non-trivial.

Yeah - this is a "trivial" fix for a difficult problem.
An alternative solution would be to disconnect all USB devices.
I'm hoping firmware doesn't enable DMA for USB ports if it doesn't find
anything.

nope, doesn't work -- i have nothing connected to the USB ports on my
c3750.
