	Dear people,

	(Please CC me as I'm not currently subscribed to linux-kernel)

	I'm trying to compile a new kernel for a PowerMac 9500/180MP
	that I just got on a loan (so that I can learn a tiny bit
	about PowerPCs) and I originally installed Debian's woody on
	it (since this is the distribution with which I feel most
	comfortable).

	Even though MacOS 8.6 runs perfectly (and fast) with it, I was
	having serious problems getting X 4 working with the IMS TT
	video card on it and, searching the web, I found out that it
	was probably because the card was not being listed on the PCI
	devices list (e.g., the card does not show with lspci) and
	that a newer 2.4 kernel would possibly cure the problem
	(Debian's default kernel is a 2.2.19 or something like that).

	After having serious headaches, I tried grabbing benh's kernel
	tree and compiled a brand new kernel for my computer. But I
	couldn't get it booting, since it always Oopsed, even BEFORE
	init was called.

	Then, I tried installing Yellow Dog Linux. Its default kernel
	is also a 2.2.19 that works perfectly, but still I could not
	get X working with the imstt driver (but now I can, at least,
	use the fbdev driver). Then, I tried compiling a new 2.4
	kernel, taken from rsync.peguinppc.org, the bitkeeper "stable"
	2.4 kernel. The precise version that I got was 2.4.10-pre12.

	It still generated an Oops, consistently and with the same
	values for the registers and memory positions. Now, I wrote
	down the Oops (since init was not even started at the time of
	the Oops it was not in the logs) and decoded it with ksymoops.

	So, can anybody help me please compiling a new kernel 2.4 for
	this machine?

	The files taken from /proc were grabbed with kernel 2.2.19-1k
	(from Yellow Dog Linux), since as described above, I couldn't
	get the system to start with 2.4.x.

	I see that the format of an Oops for PowerPC is different from
	that of x86 and that may be the cause of the warning. Is there
	anything that I can do to make ksymoops output more readable?
