<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I got an 'Bus Error' when tried to access 'mmap' PCI memory on PPC440GX machine.<BR>I verified this behavior with D-Link Ethernet Network card and Broadcom device.<BR>I have appeneded the log for reference.<BR></FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2>But the same program works fine on i386 machine i.e. accessing 'mmap' PCI memory works fine.</FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>Any clue or solution for this problem on PPC440GX machine?</FONT></DIV>
