NewWorld "Blue & White" Mac Powerpc install -- problems with firewire and aec62xx driver.

[Rick Thomas]

Nope.  Never did get it resolved.

I think it will take a custom recompile of the kernel with the assumed 
bus speed jammed to 33MHz (or maybe 66MHz) for that card.

The reason I think this (hit it with a hammer) approach might work is 
that the Debian 2.6.8 kernel has the same problem on my B&W, but the 
same (Debian) kernel works fine on my beige G3 mini-tower.  Some 
debugging messages I saw in the "dmesg" output (early boot-time kernel 
console messages -- before syslog starts up) on the Beige indicate that 
the PCI bus speed is being assumed to be set to 33MHz for this machine. 
I don't see similar messages on the B&W.  So I'm guessing that the B&W 
gives the kernel an optimistic idea of it's native bus speed.  I'm 
further guessing that the Beige is either more honest or doesn't report 
any bus speed at all.   So I'm guessing that this is what causes the 
problem on the B&W.

I'll give it a try when I've got the time.


Keep in touch!  Let me know what you find out.  And CC the list.  There 
are probably others out there with similar problems.

Even though YDL support staff don't seem to read the list, the users 
community does pretty well on it's own, and deserves all the relevant 
data we can give them.

Enjoy!
