Re: 2.4.9-bk and X on 6500, not so good

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

I have a stock 6500/300, on which I just compiled and installed the
ppc.bitkeeper linuxppc_2_4 (2.4.9) kernel. In console mode (RL3) it
works just fine.

But whenever I launch X (Gnome for example, or a plain window
manager), about 70% of the time it breaks into the mon debugger
before X has fully launched.

Problem is, there is no keyboard response at this point, and I can't
even restart with the 3-fingered approach (no response). Only thing
that works is power down, and restart.

Any suggestions? To create a backtrace appears impossible...
You can at least get the PC and LR values displayed by xmon and
lookup them in your System.map. Eventually, you can hack xmon
entry point to do a backtrace automatically.

Ben.
