I found in ./drivers/i2c/i2c-rpx.c in rpx_iic_init the structure member
ii->iic_rpbase != 0. Very likely because ppcboot uses this area as initial
stack. This causes the kernel to get a machine check during i2c init. Should
the CPM RAM not be zero'd somewhere during kernel boot?

Which kernel version are you talking about?

2.4.2 MontaVista HH linux

I think we fixed this in our version of the 8xx I2C driver long ago.

Thanks, I'll check out a newer kernel.
