I have a suspicion. After asking someone with a Sparc with an IGA1682 chip (the predecessor to the CyberPro 2000, but mostly register compatible) to try our cyber2000fb driver, it appears their chip caused the machine to NMI while accessing the chip. On an x86 PC, this normally means "system error". On the netwinder, we turn off all the PCI SERR and PERR reporting (although some still gets through). I suspect that the same sort of thing is happening on the CATS, and its throwing the hardware into madness. The solution? I have no idea - I don't have any clues to suggest why these chips behave like this, nor what tweaks may be needed to make them behave. However, there are rumours around that indicate that IGS did admit that the PCI parity logic inside the CyberPro chips were broken. _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
