[parisc-linux] kernel dies: [Was: C3000 video options]

[Elliott Potter]

Well ... I'm working on this PCI graphics card problem, and needed to
recompile the kernel.  I got the 2.4.24-pa0 kernel and built it, but
when I boot I get:

... and then it dies.  Searching on the internet for "Kernel Fault:
Code=15" I see a few e-mails that went around 3 or 4 years ago but
nothing current.  Does that mean this is a solved problem?



As far as making the Matrox Millennium go, the firmware doesn't appear
know what to do with the card, so it sticks to serial console.  From
there we can see:

information -> sysconfig says:

(sorry about the wrapping; basically it sees the card, knows it's a VGA
card, but has no firmware driver for it).

And now it's 1am so I'm going to stop.  But my goal is to make this go
:)
